Introduction

The collapse of industrial civilization is often imagined as a distant, almost cinematic event, triggered by war, pandemic, or sudden resource exhaustion. Yet the most credible threat may be the slow, relentless encroachment of the sea—a process already underway, driven by the warming atmosphere and the melting of ancient ice. Recent advances in paleoclimate research, especially the high-resolution peat records from the North Sea (Hijma et al., 2025) and comprehensive ice sheet modeling (Stokes et al., 2025), reveal that our current trajectory is not simply a gradual rise in sea level, but a potential reactivation of catastrophic processes last seen at the end of the last Ice Age. Together, these studies paint a picture of a world on the brink of a transformation that could overwhelm the foundations of modern society.

I. Paleoclimate Lessons: The Early Holocene Analogy

The early Holocene, as reconstructed by Hijma et al. (2025), was a period of extraordinary sea level rise—nearly 38 meters between 11,000 and 3,000 years ago, with two distinct pulses reaching 8–9 mm per year. These rates, driven by synchronous meltwater pulses from both the North American and Antarctic ice sheets, are far faster than today’s global average and illustrate the climate system’s capacity for rapid, nonlinear change. In practical terms, this means that if similar feedbacks or synchronous ice sheet instabilities are triggered by ongoing anthropogenic warming, modern society could face much faster SLR than current averages or conservative projections suggest. The paleoclimate record thus acts as a warning: under certain conditions, the pace of SLR can shift abruptly, overwhelming adaptation efforts and posing severe risks to coastal infrastructure, populations, and economies within much shorter timescales than policymakers or planners might expect

These findings underscore that the rates of change seen in the early Holocene are not only possible but likely under continued anthropogenic warming. The paleoclimate record shows that large-scale landscape loss, human displacement, and the submergence of entire regions—such as Doggerland, the now-lost landmass that once connected Britain to Europe—are not hypothetical, but historical realities.

II. Modern Parallels: Ice Sheet Instability and Committed Sea Level Rise

Building on the paleoclimate foundation, Stokes et al. (2025) provide a comprehensive assessment of the current vulnerability of the Greenland and Antarctic ice sheets, focusing on the feedback mechanisms that can drive rapid, nonlinear, and potentially irreversible ice loss. Their synthesis of paleoclimate data, satellite observations, and advanced ice sheet models reveals that the thresholds for triggering such feedbacks are alarmingly close—possibly already crossed under today’s warming of approximately +1.2°C above pre-industrial levels.

Key mechanisms include:

Surface elevation feedbacks on Greenland: As the ice sheet melts, its surface lowers in elevation, exposing it to warmer air at lower altitudes. This accelerates melting, which further lowers the surface, creating a self-reinforcing feedback loop. This process has been implicated in the rapid collapse of parts of the North American Ice Sheet during the last deglaciation, which contributed almost 4 meters of sea level rise per century. Central-west Greenland is now thought to be approaching a similar critical transition under current climate forcing, suggesting that this feedback could soon be fully activated.
Marine Ice Sheet Instability (MISI) in West Antarctica: Much of the West Antarctic Ice Sheet (WAIS) is grounded below sea level on bedrock that slopes downward inland (a retrograde slope), making it highly vulnerable to ocean-driven melting. When warm ocean water thins the floating ice shelves near the grounding line, the grounding line retreats into deeper water, where the ice is thicker. This increases ice discharge into the ocean, further retreating the grounding line and perpetuating the instability. Recent modeling and observations indicate that present-day ocean thermal forcing may already be sufficient to initiate slow grounding-line retreat, followed by a phase of rapid mass loss over about 200 years, potentially raising global sea level by at least a meter. Notably, the collapse of Thwaites and Pine Island Glaciers—key outlets of the WAIS—appears likely under current conditions, and once set in motion, this process could become self-sustaining.
Marine Ice Cliff Instability (MICI): This hypothesized mechanism posits that when tall, unsupported ice cliffs—exposed after the loss of buttressing ice shelves—exceed a certain height (around 90–100 meters above sea level), they may collapse under their own weight. This could trigger a self-sustaining cycle of cliff failure and rapid ice sheet retreat, potentially resulting in multi-meter sea level rise per century. While the exact likelihood and timescales of MICI are still debated, the possibility of such abrupt, catastrophic ice loss adds significant uncertainty and risk to future projections.

Both studies emphasize a critical point: there is a substantial lag between atmospheric warming and the full response of the ice sheets. This means that even if greenhouse gas emissions were halted immediately, several meters of sea level rise are already “locked in” over the coming centuries due to processes already set in motion. The paleoclimate record from the North Sea, with its evidence of sudden, multi-meter pulses of sea level rise, underscores that these changes can occur not just gradually but in abrupt surges.

Furthermore, the current rates of ice mass loss from Greenland and Antarctica are already accelerating. Observations show that the WAIS, in particular, is losing mass at rates that, if sustained or increased, could lead to rapid deglaciation scenarios. The loss of ice shelves through processes such as long-term thinning, basal melting, and surface ponding makes the remaining ice more vulnerable to collapse, and the removal of these buttressing shelves can dramatically speed up glacier flow and grounding line retreat.

In summary, the modern parallels to past episodes of rapid sea level rise are clear and deeply concerning. The feedback mechanisms identified in both Greenland and Antarctica have the potential to unleash non-linear, large-scale ice loss, committing the planet to significant and possibly abrupt sea level rise. These processes, already underway, highlight the urgent (and persistently ignored) need for both aggressive mitigation and robust adaptation strategies, as the window to prevent the most extreme outcomes continues to narrow.

III. The Inadequacy of Current Climate Targets

The Paris Agreement’s goal of limiting global temperature rise to +1.5°C above pre-industrial levels is widely regarded as the “safe” threshold for avoiding catastrophic climate impacts. However, both Stokes et al. (2025) and Hijma et al. (2025) present compelling evidence that this target is dangerously insufficient, particularly when it comes to sea level rise and ice sheet stability.

Stokes et al. (2025) make clear that even at today’s warming of approximately +1.2°C, the world is already committed to substantial ice loss from both Greenland and Antarctica. Their analysis of paleoclimate analogs, combined with contemporary ice sheet modeling, shows that the thresholds for triggering irreversible feedbacks—such as surface elevation feedbacks on Greenland and marine ice sheet instability in West Antarctica—may already have been crossed or are perilously close. Once these processes are initiated, they are largely self-sustaining and continue to drive ice loss and sea level rise for centuries or even millennia, regardless of future emissions reductions.

Moreover, Stokes et al. highlight the dangers of “overshoot” scenarios, in which global temperatures temporarily exceed the 1.5°C target before eventually being brought back down through mitigation or carbon removal. Their findings indicate that each decade spent above 1.5°C adds a measurable and irreversible increment to long-term sea level rise, even if temperatures are later reduced. This is because the physical processes governing ice sheet disintegration operate on much longer timescales than the political or economic cycles that drive emissions. Once critical thresholds are crossed, the resulting ice loss cannot simply be reversed by cooling the climate; the system is committed to a new, higher equilibrium sea level that may take thousands of years to stabilize.

The early Holocene record, as reconstructed by Hijma et al. (2025), reinforces this conclusion. Their high-resolution North Sea peat data show that even relatively modest and sustained increases in global temperature—far below the levels projected for the coming centuries—were sufficient to unleash rapid, multi-meter pulses of sea level rise. These events were not gradual or easily managed; they fundamentally reshaped coastlines, submerged vast areas of habitable land, and forced large-scale human migrations. The implication is that the Earth system’s response to warming is highly sensitive and nonlinear, with the potential for abrupt and irreversible changes even under seemingly moderate climate scenarios.

Perhaps most troubling, both studies emphasize that the timescales for ice sheet regrowth and sea level stabilization are measured in millennia, not decades or centuries. This means that the impacts of decisions made today—whether to allow further warming, to overshoot targets, or to delay mitigation—will reverberate for countless generations. The feedbacks that drove early Holocene sea level rise are not relics of the past; they are reactivating under current conditions, and their consequences will be effectively permanent on any human timescale.

In summary, the integrated evidence from Stokes et al. and Hijma et al. reveals that the Paris Agreement’s targets are scientifically inadequate for preventing dangerous sea level rise. The Earth system’s response to warming is not gradual, linear, or easily reversible. Instead, it is characterized by thresholds, feedbacks, and long-term commitments that demand far more urgent and aggressive action than current international goals and policies provide.

IV. The Cascading Impacts on Industrial Civilization

Economic and Infrastructural Collapse

The direct impacts of sea level rise—flooded cities, submerged infrastructure, and lost agricultural land—are well known, but the integration of recent studies reveals the alarming speed and scale at which these impacts can accumulate. If early Holocene rates of 8–9 mm/year are matched or exceeded in the coming centuries, as paleoclimate evidence and some modern projections warn, the world could see a meter or more of sea level rise within a human lifetime. This scenario would have profound and far-reaching consequences for industrial civilization.

Ports and Trade: Major ports, through which 90% of global trade flows, are concentrated in low-lying coastal zones. A meter or more of sea level rise would render many of these ports inoperable, disrupting global supply chains and causing cascading failures in international commerce.
Real Estate and Infrastructure: Trillions of dollars’ worth of coastal real estate could become submerged or uninsurable, with recent studies projecting that the economic costs to coastal cities could exceed $3 trillion by the end of this century. The costs of maintaining, repairing, or relocating infrastructure—including roads, bridges, and utilities—will skyrocket, straining municipal and national budgets.
Energy Systems: Refineries, power plants, and other critical energy infrastructure are disproportionately located near coastlines for access to shipping and cooling water. Rising seas and increased flooding threaten to disrupt energy production and distribution, increasing the risk of blackouts and fuel shortages.
Agriculture and Water: Fertile deltas and estuaries, which support hundreds of millions of people, are at risk of inundation and saltwater intrusion, leading to the loss of arable land and the contamination of freshwater supplies. This could trigger food crises and mass displacement in some of the world’s most densely populated regions.

Social and Political Destabilization

The loss of habitable land and economic assets will not be evenly distributed, amplifying existing inequalities. As Stokes et al. (2025) note, each centimeter of sea level rise can displace a million people. The early Holocene saw the abandonment of entire regions such as Doggerland; today, similar displacement would occur on a scale unprecedented in human history, potentially affecting hundreds of millions of people. This mass migration would strain social services, increase competition for resources, and heighten the risk of humanitarian crises and conflict over dwindling land and water.

Insurance and Financial Systems: Insurance markets are already retreating from high-risk coastal areas, and a collapse of these markets could trigger housing market crashes and broader fiscal crises. As the costs of defending or relocating infrastructure outpace available resources, governments will be forced into triage decisions, deepening social divisions and unrest.
Urban Vulnerability: By 2050, up to 800 million people could be living in cities at risk from sea level rise and coastal flooding, with economic costs to cities alone projected to reach $1 trillion by mid-century. Cities like New York, Miami, Shanghai, Mumbai, and Dhaka are especially vulnerable, facing both asset losses and large populations at risk of displacement.

Geopolitical Flashpoints

The melting of polar ice is not only a threat to existing centers of power but also opens new frontiers for resource extraction and geopolitical competition. The Arctic is rapidly becoming a zone of military and economic contest as nations vie for control over newly accessible oil, gas, and shipping lanes. Meanwhile, low-lying island nations and coastal megacities face existential threats, with little recourse but to seek international aid or, in the worst case, abandon their territories altogether.

Regional Shifts: As coastal regions decline, some inland areas may see relative economic gains as production and population shift away from flood-prone zones. However, this redistribution is unlikely to offset the massive global losses and will bring its own challenges, including infrastructure needs and social integration for climate migrants.
International Tensions: The displacement of large populations and the scramble for new resources could fuel international tensions, particularly in regions where borders are already contested or where resources are scarce.

In sum, the cascading impacts of sea level rise—economic, social, and geopolitical—threaten to undermine the foundations of industrial civilization. The speed at which these impacts could unfold, as demonstrated by both paleoclimate analogs and emerging scientific projections, underscores the urgent (and persistently ignored) need for comprehensive adaptation and mitigation strategies at every level of society.

V. The Adaptation Mirage and the Limits of Engineering

Both Stokes et al. (2025) and Hijma et al. (2025) express deep skepticism about the long-term viability of relying on engineering solutions—such as seawalls, levees, pumps, and barriers—to keep pace with accelerating sea level rise. While these measures can provide temporary protection and buy time for vulnerable communities, their effectiveness diminishes as the rate and magnitude of sea level rise increase. The cost of defending every vulnerable coastline is not only prohibitive but also subject to diminishing returns, especially as many cities are also contending with land subsidence, which can cause local relative sea levels to rise even faster than the global average.

Recent engineering experience and scientific analysis reinforce these concerns. Hard infrastructure like seawalls and levees can create a false sense of security, encouraging further development in at-risk areas—a phenomenon known as the “Safe Development Paradox.” When such defenses are eventually overtopped or breached by extreme events, the resulting damage is often even greater because more assets and people have been concentrated behind the barriers. Moreover, the maintenance costs for these structures escalate over time, and their design lifespans may be outstripped by the accelerating pace of sea level rise. For example, static, one-time investments in coastal defenses may prove inadequate if sea levels rise faster than projected, leading to costly retrofits or failures.

Flexible, adaptive approaches—such as incrementally raising seawalls or updating flood management strategies in response to observed changes—can be more cost-effective and reduce the risk of catastrophic outcomes. However, even these dynamic strategies have limits, especially as high-end projections for sea level rise approach or exceed a meter by 2100. In many cases, especially in low-lying or subsiding areas, the technical, financial, and social challenges of perpetual defense become insurmountable.

The paleoclimate record underscores the danger of overreliance on engineered defenses. Once thresholds are crossed, the pace of change can rapidly accelerate, overwhelming even the best-prepared societies. The early Holocene saw entire landscapes disappear beneath the sea in a matter of centuries, a rate of change that would outstrip the capacity of any modern engineering project to keep pace.

Given these realities, managed retreat—abandoning the most vulnerable areas in a planned and coordinated way—emerges as a necessary, if politically and socially challenging, adaptation strategy. Managed retreat involves relocating people, assets, and infrastructure away from high-risk zones, often through buyout programs, zoning changes, and restoration of natural coastal buffers. While this approach can be contentious and disruptive, it is increasingly recognized as the only viable long-term solution for many communities facing chronic inundation and escalating disaster risk.

Implementing managed retreat at scale requires significant political will, social consensus, and massive investment—all of which are often in short supply. Public resistance, legal hurdles, and the emotional and cultural ties people have to their homes present formidable obstacles. Successful examples of managed retreat, such as those in parts of New Zealand, Hawaii, and the Caribbean, demonstrate that with careful planning, community engagement, and supportive policies, relocation can be an opportunity to redesign safer, more resilient, and even more equitable coastal communities. However, these cases remain the exception rather than the rule, and most adaptation efforts worldwide still focus on protection and accommodation rather than retreat.

In summary, while engineering solutions will remain part of the adaptation toolkit, the accelerating pace and scale of sea level rise revealed by both paleoclimate and modern science mean that they cannot be the sole or ultimate answer. Societies must confront the difficult (and mostly ignored) reality that some places will need to be abandoned, and that proactive, well-planned managed retreat may offer the best chance to reduce long-term losses and build resilience in the face of an inexorably rising sea.

VI. Lessons from Doggerland: The Human Cost of Inaction

The drowning of Doggerland, as reconstructed by Hijma et al. (2025), stands as a powerful cautionary tale for our time. Doggerland was once a vast, fertile landscape stretching between present-day Britain, the Netherlands, Germany, and Denmark, serving as a crucial corridor for human migration and cultural exchange between continental Europe and the British Isles.Archaeological finds—including stone tools, animal bones, and even human footprints—demonstrate that Doggerland supported thriving Mesolithic communities, with abundant resources that encouraged both permanent and semi-permanent settlements.

As the last Ice Age ended and global temperatures rose, melting glaciers caused sea levels to rise steadily. Between 10,000 and 7,000 years ago, Doggerland was gradually inundated, breaking up into a series of low-lying islands before finally slipping beneath the waves of the North Sea.This transformation was not a single, sudden event but a drawn-out process punctuated by episodes of rapid change, such as those triggered by meltwater pulses and possibly catastrophic events like the Storegga Slide tsunami around 6200 BCE. The submergence of Doggerland ultimately cut off Britain from the European continent, fundamentally altering the geography and human history of the region.

The archaeological and geological evidence suggests that the people of Doggerland were forced to adapt, migrate, or perish as their homeland disappeared. Some may have moved to higher ground, contributing to the spread of Neolithic culture and agriculture in the British Isles.Others likely faced hardship, loss of resources, and the trauma of displacement. The gradual but relentless encroachment of the sea would have repeatedly upended lives, destroyed settlements, and erased entire landscapes from human memory.

Today, we face a similar reckoning, but on a vastly larger scale. The modern world’s coastal cities, deltas, and low-lying nations are home to hundreds of millions—far more than the Mesolithic populations of Doggerland. The difference, however, is that we have forewarning. High-resolution paleoclimate data and modern modeling now allow us to anticipate the risks and visualize the potential futures that unchecked sea level rise could bring. The lessons of Doggerland are not just academic: they are a direct warning about the consequences of inaction.

Yet, knowledge alone is not enough. The inertia of the Earth system—where ice sheet responses to warming unfold over centuries or millennia—means that much of the coming sea level rise is already set in motion. At the same time, the inertia of human systems—political, economic, and social—slows our ability to respond effectively. Delays in adaptation, denial of risk, and the immense challenge of relocating populations and infrastructure all threaten to repeat the tragedies of the past, but on a scale never before witnessed.

Doggerland reminds us that entire societies can be lost to the sea, their stories only rediscovered millennia later by archaeologists dredging the seabed. The fate of Doggerland’s people—forced to migrate, adapt, or disappear—foreshadows the stark choices facing coastal populations today and the dire consequences for delaying action.

VII. Predicting the Timing and Nature of Collapse

The Next Century: From Chronic Crisis to Systemic Failure

If current emissions trends persist, both Hijma et al. (2025) and Stokes et al. (2025) indicate that the world will move from a period of chronic, somewhat manageable coastal challenges to an era of acute, systemic failures—potentially within a single century. The early Holocene’s rapid sea level rise pulses, as revealed by the North Sea peat records, serve as a sobering analogue for what could occur if the Greenland and Antarctic ice sheets cross their respective tipping points. These tipping points are thresholds beyond which ice loss accelerates rapidly and becomes largely unstoppable, even if temperatures stabilize or decline later.

By 2100, a global mean sea level rise of one meter or more is plausible—well within the range of high-end projections, especially if non-linear ice sheet responses are triggered. This level of rise would have profound, cascading consequences:

Overwhelming Urban Defenses: Existing coastal defenses in major cities such as New York, Shanghai, Mumbai, Jakarta, London, and Miami would be overwhelmed. Many of these cities are already experiencing regular tidal flooding, and a meter of additional sea level would render current infrastructure obsolete, exposing millions to chronic inundation and storm surges.
Mass Displacement: Conservative estimates suggest that tens to hundreds of millions of people would be forced to relocate from low-lying coasts, river deltas, and island nations. The logistical, economic, and social challenges of such mass migration are unprecedented in human history, with the potential to destabilize entire regions.
Cascading System Failures: Food production would be disrupted as fertile deltas and coastal farmlands are lost to salinization and flooding. Energy systems—particularly those reliant on coastal infrastructure—would become increasingly vulnerable, and the global trade network would be thrown into chaos as ports are submerged or rendered inoperable. These interconnected failures could ripple through supply chains, leading to shortages, inflation, and widespread hardship.
Fiscal Collapse: The costs of defending, relocating, or abandoning coastal infrastructure would strain national and municipal budgets to the breaking point. Insurance markets could collapse, property values could plummet, and the fiscal solvency of states—especially those with large coastal populations and assets—could be undermined, triggering broader economic crises.

The transition from chronic to acute crisis would not be a singular, dramatic event but a series of escalating shocks—each one eroding the resilience of social, economic, and political systems. As the frequency and severity of coastal disasters increase, the ability of governments and communities to respond effectively will diminish, accelerating the slide toward systemic failure.

The Long View: Irreversible Transformation

Looking beyond the next century, the paleoclimate record and current modeling suggest that several meters of sea level rise are all but inevitable over the coming centuries to millennia, even if emissions are sharply reduced. The inertia of the Earth system means that the processes set in motion today will continue to unfold long after current generations are gone.

Redrawing the World’s Map: Multi-meter sea level rise would permanently redraw global coastlines, submerging entire nations—such as the Maldives, Tuvalu, and parts of Bangladesh—and erasing iconic cities and cultural heritage sites. The loss of coastal land would force a reorganization of human civilization on a scale not seen since the end of the last Ice Age, when the flooding of Doggerland and other lowlands fundamentally altered the course of human history.
Permanent Loss of Infrastructure and Livelihoods: Ports, airports, industrial zones, and entire cities would be lost to the sea, along with the livelihoods and identities tied to those places. The economic and psychological toll of such loss is difficult to quantify but would be immense.
Ecological Shifts: The transformation of coastlines would also have profound ecological consequences, altering habitats for countless species and disrupting the delicate balance of coastal and marine ecosystems.

The nature and pace of this collapse will be shaped by the actions taken in the coming decades. If humanity acts decisively to limit warming, aggressively reduce emissions, and invest in adaptation and managed retreat, the transition may be managed—painful, costly, and disruptive, but not necessarily catastrophic. Societies could adapt to new coastlines, develop resilient infrastructure, and find ways to support displaced populations.

However, if action is delayed or insufficient (delay, deny, and obfuscate has been and continues to be the playbook of corporate capitalism), then the collapse is likely to be chaotic, violent, and irreversible. The combination of accelerating sea level rise, social and political instability, and economic breakdown will lead to a future where large regions become ungovernable, humanitarian crises become chronic, and the achievements of industrial civilization are swept away by the rising tide.

Silent Sentinels of Doom: The Nuclear Plants That Will Outlive Us

Humanity’s nuclear legacy stands as one of the most dangerous and long-lasting threats to our species’ survival in a collapsing world. With 440 operational reactors, 223 permanently shuttered reactors, and over 435,000 tons of high-level radioactive waste stored in vulnerable facilities worldwide (IAEA, 2023), we have created a radioactive sword of Damocles that hangs over future generations. As climate chaos destabilizes institutions and infrastructure, these nuclear sites risk catastrophic failure that could render vast regions uninhabitable for centuries, compounding the existential threats of biodiversity collapse and climate feedback loops. Recent studies from 2023-2025 reveal even greater risks than previously understood, from climate-vulnerable coastal reactors to Russia’s dangerous floating nuclear plants and new evidence about the precarious state of Chernobyl’s containment.

Coastal and Inland Reactors: The Dangers of Rising Seas, Floods, & Droughts

The siting of nuclear reactors has created what experts now recognize as one of the most serious climate vulnerabilities of the 21st century. Recent studies project that over 40% of the global nuclear fleet, situated in coastal zones, faces escalating threats from sea-level rise (Portugal-Pereira, Esteban, and Araújo 2024), with the IAEA identifying 40+ priority sites (IAEA 2023). Over 60% of U.S. plants are in high-flood zones, and 20% face significant wildfire risks. Coastal facilities, like California’s Diablo Canyon, confront sea level rise projections of up to 1.2 feet by 2050 (U.S. GAO 2024). Meanwhile, storms and wildfires disrupt operations through grid instability, debris-clogged intakes, and worker safety risks, with U.S. NPPs losing 190 production days to weather events from 2011–2020 (EPRI 2023, 7, 16–17).

As of 2024, nearly 70% of global reactors are now operating beyond their original 30-year lifespans, with dozens pushing 40+ years of operation, creating a perfect storm of deferred decommissioning and mounting safety risks. By 2050, almost all U.S. nuclear reactors will have reached their 60 year maximum expected life (Alley and Alley 2014). In a world teetering on collapse, the glacial pace of nuclear decommissioning—stretching 30 to 100 years for a single reactor—creates a dangerous paradox: humanity’s most fragile institutions now guard its most persistent hazards, as radioactive husks outlast the civilization that built them.

A 2023 study in Energy and Environmental Science projects that under RCP8.5 (high-emissions) climate scenarios, 38–45 coastal reactors (8–10% of the global fleet) will face Category 4+ tropical cyclone risks by 2070—exceeding original design standards in 22 cases (Schmidt et al., 2023). These findings build on the hard lessons of Fukushima, where in 2011 a tsunami overwhelmed defenses and caused triple meltdowns that released 520 petabecquerels (PBq) of radiation (NAS, 2014). In a post-collapse world where maintenance and disaster response have ceased, similar accidents would occur with terrifying frequency, each one poisoning groundwater and marine ecosystems with long-lived isotopes like cesium-137 and strontium-90 that remain dangerous for centuries.

The threat extends beyond simple flooding. Prolonged heatwaves and droughts – already forcing reactor shutdowns in France during their 2022 heat emergency when Rhône River temperatures became too warm for cooling (UNECE, 2019) – will become more severe and frequent. Droughts and water scarcity, particularly in regions like the U.S. Southwest, could force 61% of U.S. plants into high-stress conditions by 2030, jeopardizing cooling capacity (EPRI 2023, 15).

The risks also extend beyond reactors themselves to the precarious storage of nuclear waste. Spent nuclear fuel (SNF) is one of the most radioactive human-made materials, requiring meticulous containment for millennia. Two-thirds of SNF is stored in pools of water on-site at the very nuclear plants where they were used, presenting a very exposed target for terrorists, natural disasters, and industrial accidents. In a collapsed society without grid power or active cooling methods, spent nuclear fuel pools (SFPs) can boil dry within 7–10 days, exposing radioactive fuel rods. Without circulating water, temperatures rise rapidly, exceeding 500–1,000°C, damaging the zirconium cladding. Zirconium burns at 900°C+, especially in air (even more aggressively than in steam). Under such a scenario, studies project cesium-137 releases of up to 100× the Hiroshima bomb—potentially contaminating thousands of square kilometers. These fires would create radioactive plumes that could contaminate entire regions downwind, rendering them uninhabitable for generations.

A study of such a scenario found that a hypothetical spent fuel pool fire at South Korea’s Kori-3 reactor could release catastrophic levels of cesium-137 (Cs-137), contaminating up to 54,000 km² of South Korea and displacing 24 million people, with significant cross-border impacts in North Korea, Japan, and China depending on weather patterns (Kang et al. 2017). Using the HYSPLIT atmospheric dispersion model, the study simulated Cs-137 releases under historical 2015 meteorological data, revealing that dense-packed fuel storage—common in South Korean reactors—amplifies risks by enabling zirconium cladding fires and hydrogen explosions, which could disperse 75% of the pool’s Cs-137 inventory (Kang et al. 2017). Compared to Fukushima, where Cs-137 forced 160,000 evacuations, the Kori-3 scenario highlights exponentially greater dangers due to higher spent fuel inventories. The authors urge transitioning older spent fuel to dry-cask storage and maintaining low-density pool storage to mitigate disaster risks (Kang et al. 2017).

SFPs at nuclear facilities present critical vulnerabilities to radiological terrorism, with potential Cs-137 releases exceeding Chernobyl’s impact by orders of magnitude due to their high radioactivity inventories and less robust structural protections compared to reactor cores (Zhang 2003). A sabotage-induced loss of cooling could ignite zirconium cladding fires, releasing up to 100% of a pool’s Cs-137—a 400-ton SFP, for instance, holds 10 times more long-lived radioactivity than a reactor core, risking contamination of 95,000 km² (over nine times Chernobyl’s affected area) from a 50% release (Zhang 2003). Attack vectors include aircraft crashes (45% breach likelihood for large planes), anti-tank missiles, or truck bombs, with reprocessing plants like France’s La Hague—housing Cs-137 inventories 280 times Chernobyl’s—posing amplified risks (Zhang 2003). Zhang advocates hardening SFP structures, transitioning to dry-cask storage, enforcing no-fly zones, and strengthening IAEA security standards to mitigate catastrophic scenarios (Zhang 2003).

Mark Leyse (2024) warns that densely packed spent nuclear fuel pools in the U.S. pose catastrophic risks, with zirconium cladding on fuel rods capable of igniting if coolant water is lost—releasing up to 24 megacuries of cesium-137, ten times Chernobyl’s release, and contaminating thousands of square miles (Leyse 2024). While the Nuclear Regulatory Commission (NRC) dismisses these risks by focusing on ultra-rare earthquakes (e.g., 1-in-60,000-year events), Leyse argues that grid collapse—from solar storms, cyberattacks, or physical sabotage—is a far likelier trigger, potentially disabling backup cooling systems and leading to nationwide meltdowns and fires (Leyse 2024). For instance, solar superstorms like the 2012 near-miss event could induce currents strong enough to melt critical transformers, causing months-long blackouts, while synchronized drone or cyberattacks (e.g., Russia’s 2015 Ukraine grid hack) could cripple infrastructure (Leyse 2024). Despite the NRC’s inaction, transferring spent fuel to dry cask storage—already mandated during decommissioning—could reduce cesium inventories by 50% and decay heat by 30% at a cost of just $5.4 billion today, a fraction of the incalculable human and economic toll of radiological contamination (Leyse 2024). Leyse urges Congress to mandate this transition, as societal collapse during prolonged grid failure would render emergency responses impossible, leaving “multiple nuclear disasters” to unfold unchecked (Leyse 2024).

Floating Nuclear Reactors: Russia’s Dangerous Experiment

While most analyses focus on land-based reactors, Russia’s development of floating nuclear power plants (FNPPs) introduces a terrifying new dimension to nuclear risk. The Akademik Lomonosov, the world’s only operational FNPP, began providing power to Pevek in Russia’s Far East in 2020 with plans for four additional floating reactors by 2035 (Rosatom, 2025). These mobile reactors are frequently excluded from global reactor counts, representing a hidden escalation of nuclear risk.

FNPPs pose unique dangers because of their locations in fragile Arctic and coastal zones where storms or sabotage could cause meltdowns in remote regions completely lacking emergency response capabilities. AMAP’s 2021 Arctic Climate Update notes accelerated corrosion in Arctic infrastructure due to reduced ice cover. Rosatom’s 2023 Technical Bulletin mentions “increased maintenance needs” for Akademik Lomonosov. In a collapsing world where maintenance ceases, these floating reactors could become drifting radiological time bombs, potentially contaminating vast stretches of coastline or even sinking and creating underwater radiation hazards that persist for millennia.

The Chernobyl Sarcophagus: A War-Torn Tomb of Radioactive Peril

The steel-clad sarcophagus entombing Chernobyl’s ruined Reactor 4 was designed to last a century. Instead, Russia’s invasion has turned this fragile containment system into a ticking time bomb. What was once humanity’s most ambitious nuclear containment project has become a monument to wartime recklessness—its structural integrity sabotaged, its monitoring systems compromised, and its radioactive contents left increasingly vulnerable to the elements.

The Occupation’s Radioactive Scars (2022-2023)

The study “Nuclear Threat Resulting from Russian Military Occupation of Chornobyl Exclusion Zone” by Nosovskyi et al assesses the nuclear safety risks and radiological threats arising from Russia’s military occupation of the Chornobyl Exclusion Zone (ChEZ) in February–March 2022. Published in atw – International Journal for Nuclear Power (May 2022), the study details vulnerabilities such as structural instability of containment systems, disruption of power and safety protocols, forest fires dispersing radioactive isotopes, and violations of international nuclear security conventions.

Brief List of Threats Described in the Study:

Structural Damage to Containment Systems: The aging Shelter Object and New Safe Confinement (NSC) are vulnerable to military attacks, explosions, or aircraft crashes, risking collapse and massive radioactive releases akin to the 1986 disaster.
Loss of Electrical Power: Prolonged blackouts (e.g., 125 hours in March 2022) jeopardized cooling systems for spent nuclear fuel pools, risking overheating, hydrogen explosions from radiolysis, and loss of ventilation/radiation monitoring.
Forest Fires in Contaminated Areas: Uncontrolled fires (March 11–18, 2022) burned radioactively contaminated vegetation, aerosolizing and dispersing isotopes like $^{137} Cs$ and $^{90} Sr$ , threatening Ukraine, Belarus, and Europe.
Radiation Exposure to Military Personnel: Soldiers digging trenches in highly contaminated zones (e.g., Red Forest) faced acute radiation doses (>250 mSv), leading to hospitalization with radiation sickness.
Disruption of Safety Systems: Occupation disabled radiation monitoring networks, firefighting capabilities, and communication, hindering emergency responses.
Shelling/Explosions Near Nuclear Facilities: Ammunition storage and military activity near ChEZ facilities risked damaging spent fuel storage sites (SNFSF-1/SNFSF-2), potentially releasing fissile materials exceeding the 1986 accident’s scale.
Criticality Risks: Disturbance of spent fuel assemblies (e.g., via explosions) could alter spacing, creating conditions for unintended nuclear reactions.
Staff Hostage Conditions: Exhausted, psychologically traumatized personnel worked under armed supervision, increasing risks of operational errors.
Cooling Pond Degradation: Dropping water levels exposed radioactive sludge, raising risks of wind-driven contamination.
Violations of International Conventions: Occupation breached IAEA’s seven nuclear safety pillars and the Convention on Nuclear Material Protection, endangering global security.

Living with the Consequences:

Decades after the 1986 Chernobyl catastrophe, a new threat looms: wildfires in these regions risk resuspending radioactive particles into the air, endangering ecosystems and human health. Each summer in Ukraine brings the chance for increasingly severe wildfires. A groundbreaking study by an international team of scientists (Ager et al. 2019) reveals where these fires are most likely to ignite, spread, and unleash radioactive plumes—and how to stop them. In August 2020, wildfires burned intensely for over 90 minutes, releasing dangerous isotopes like cesium-137, strontium-90, and plutonium into the atmosphere, with radiation levels reportedly spiking 16 times above normal near the blazes. Smoke choked Kyiv, and monitors as far as Norway detected elevated cesium, though the full scale of contamination remains uncertain due to COVID-19 restrictions that prevented on-site measurements during the crisis. These fires underscore the collision of climate-driven disasters with Chernobyl’s radioactive legacy, as rising temperatures and dry conditions fuel seasonal blazes that risk remobilizing long-buried toxins from the 1986 disaster (Little 2020).

Wildfires in Chernobyl’s abandoned forests could unleash a “second nuclear disaster,” warns Evangeliou et al. (2014). Modeling three scenarios—10%, 50%, and 100% of contaminated forests burning—the study projects radioactive cesium-137 (¹³⁷Cs) plumes dispersing across Europe, emitting 0.29–4.2 PBq of radiation. High-risk zones include densely populated Central and Eastern Europe, with 10–170 potential cancer fatalities from inhalation and contaminated food chains. While direct ecological harm is minimal, fungi bioaccumulation threatens local diets. The authors rank large fires as International Nuclear Event Scale (INES) level 6 accidents, comparable to historic disasters like Kyshtym. Climate change and political instability in Ukraine exacerbate risks, demanding urgent forest management to avert a preventable crisis (Evangeliou et al. 2014).

A Shortened Doomsday Clock

A recent drone strike on February 14, 2025 critically damaged the protective arch over Chernobyl’s reactor, leaving the structure unable to fully contain radioactive materials and prompting urgent calls for international reconstruction efforts. Experts warn that without swift repairs, the compromised shield could undermine decades of work to prevent further radioactive contamination from the 1986 disaster (Grzmiel 2025). In a post-collapse environment where maintenance has ceased, Chernobyl’s radioactive demons will inevitably be released back into a world incapable of containing them; but that time may come much sooner.

An Evolving Frontline (2022-Ongoing)

Russia’s impact on Ukraine’s nuclear facilities was not confined to Chernobyl. Russian forces have weaponized nuclear safety by militarizing the ZNPP, creating risks of accidental catastrophe. The IAEA has repeatedly condemned these actions as violations of international nuclear safety protocols. According to the OECD Nuclear Energy Agency (n.d.), Ukraine’s nuclear power infrastructure remains under close scrutiny due to ongoing geopolitical risks:

2022

March 4: Russian forces seize control of the Zaporizhzhia Nuclear Power Plant (ZNPP) after shelling the facility. A fire breaks out in a training building, but reactors remain intact (IAEA 2022; BBC 2022).
August 5–6: Shelling near the ZNPP damages radiation sensors, a nitrogen-oxygen station, and power lines, prompting warnings from the IAEA (Reuters 2022).
August 25: The ZNPP is temporarily disconnected from Ukraine’s power grid for the first time due to shelling, raising fears of a potential meltdown (IAEA 2022).
September 1: IAEA inspectors arrive at the ZNPP after weeks of negotiations. They report structural damage but no immediate radiation threat (UN News 2022).
September 11: The ZNPP’s last operational reactor is shut down due to shelling risks, transitioning the plant to “cold shutdown” mode (IAEA 2022).

2023

May 22: Russian forces reportedly withdraw some personnel from the ZNPP, raising concerns about operational safety (Kyiv Independent 2023).
June 22: The Kakhovka Dam (critical for cooling the ZNPP) is destroyed, threatening the plant’s water supply. The IAEA calls for urgent safeguards (BBC 2023).
July 4–5: Explosions occur near the ZNPP, damaging windows and infrastructure. Russia and Ukraine accuse each other of shelling (Reuters 2023).

2024

April 7: The International Atomic Energy Agency (IAEA) reported that drone attacks struck reactor Unit 6 at the ZNPP.
August 11: The IAEA team at ZNPP reported that Russian operators informed them of an alleged drone attack on one of the plant’s cooling towers.
August 26: Widespread strikes on Ukraine’s energy infrastructure, including the South Ukraine NPP and the Rivne NPP, caused power outages and led to the temporary shutdown or disconnection of reactor units.
November 16-17: Attacks on four substations and power lines prompted all operating nuclear power plants to reduce power output, including the South Ukraine NPP.
November 17: A large-scale Russian missile attack on Ukraine’s electricity system caused significant damage to electric substations, including those vital to the operation of nuclear power plants.
December 10: An IAEA vehicle was hit by a Russian drone while transporting observers to the ZNPP.

2025

February 14: A Russian drone struck the roof of the New Safe Confinement (NSC) structure at Chernobyl. The IAEA said that both the outer and inner cladding of the NSC’s arch had been breached, but that radiation levels were stable.

Post-Collapse Meltdowns: New Modeling Reveals Greater Risks

Recent advanced simulations paint an even grimmer picture of what nuclear infrastructure failure would look like in a collapsing civilization. Nuclear reactors require continuous cooling even after shutdown, and in a power grid collapse scenario, backup diesel generators (typically with 4–8 hours of fuel) and batteries (lasting ~8 hours in older plants) are the last line of defense to keep nuclear fuel rods cool via water circulated by pumps. If grid power isn’t restored within this window, fuel pools and reactor cores risk overheating, potentially leading to meltdowns. The coolant water will boil and evaporate away. The Nuclear Regulatory Commission (NRC) mandates 4–8 hours of backup power for reactors, assuming grid restoration within that window. Newer plants, like the AP1000 design, can operate for 72 hours without intervention. A 2023 study by Oak Ridge National Laboratory (ORNL) explored how electromagnetic pulses (EMPs) — including those generated by nuclear detonations or portable microwave weapons — could cripple power plants by overwhelming critical electronics, transformers, and control systems (ORNL 2023). The research team, collaborating with Lawrence Livermore National Laboratory and the University of Tennessee, modeled EMP impacts using ambient electromagnetic signals and simulations, revealing vulnerabilities in low-voltage components like inverters and motors. Their findings emphasize that modern grid infrastructure, including solar arrays and wind turbines, is particularly exposed due to reliance on semiconductors and inadequate surge protection. The study recommends enhanced shielding, grounding, and facility design to mitigate cascading failures that could trigger prolonged blackouts (ORNL 2023). No U.S. plant is designed to handle indefinite blackouts. The NRC’s 2023 review focuses on enhancing battery life and portable generators but doesn’t address global collapse.

The other temporary method for storing SNF is in dry casks which are massive structures (50-200 tons each) made of thick steel and concrete, each one holding 15–20 metric tons of spent fuel. Only a third of America’s spent nuclear fuel (SNF) is stored in dry casks. Manufacturing, monitoring, and maintaining of these casks incur significant long-term expenses. Dry casks were typically intended to safely store spent nuclear fuel for 40 to 100 years. This timeframe bridges the gap between reactor discharge and permanent disposal in a deep geological repository. (“Reactor discharge” refers to the removal of spent nuclear fuel from a nuclear reactor after it has been used to generate energy). However, delays in establishing permanent repositories have led to their use extending beyond original expectations, raising concerns about aging effects not fully studied in original design (e.g., material fatigue, seal degradation). Over 90,000 metric tons of spent fuel are currently in storage nationwide, with most now in dry casks. The U.S. adds 300–400 new casks annually due to ongoing reactor operations and the lack of a permanent disposal site. The US currently stores about 3,800 dry casks and by 2050, the total could exceed 10,000 casks if no permanent repository is established. That future number does not take into consideration for any future build-out of new nuclear plants.

A Stanford University and University of British Columbia study challenges the purported benefits of small modular reactors (SMRs), revealing that these next-generation nuclear systems may produce significantly more radioactive waste than conventional reactors (Krall et al., 2022). Published in Proceedings of the National Academy of Sciences on May 31, 2022, the research analyzed three SMR designs and found that their compact size leads to increased neutron leakage, irradiating structural materials and generating up to 30 times more waste by volume compared to traditional plants. This includes at least ninefold higher quantities of neutron-activated steel and chemically complex spent fuels requiring costly pretreatment (Krall et al., 2022). Lead author Lindsay Krall emphasized that SMRs’ spent fuel is not only bulkier but also more radiotoxic, with plutonium remains retaining 50% higher radiotoxicity after 10,000 years, complicating long-term disposal (Krall et al., 2022). Co-author Rodney Ewing noted that the U.S. lacks a viable geologic repository program, forcing reliance on insecure interim storage as SMR waste accumulates. The study refutes industry claims of cost and waste reduction, urging developers to address these “hidden costs” and prioritize transparent waste management research. With the nuclear industry promoting SMRs as a climate solution, the findings underscore critical environmental and economic trade-offs that could hinder their viability.

The thawing of Arctic permafrost poses a significant threat to nuclear waste containment. Historically, both the Soviet Union and the United States deliberately stored toxic and radioactive materials in permafrost, assuming it would remain permanently frozen (Langer et al. 2023). Rising temperatures now destabilize these sites, risking the release of hazardous substances through compromised infrastructure or hydrological pathways.

Key examples illustrate this risk:

Kraton-3 (Russia): Radioactive byproducts from a 1978 nuclear explosion (Artamonova et al. 2013);
Camp Century (Greenland): Abandoned U.S. military waste, including nuclear coolant (Colgan et al. 2016);
Project Chariot (Alaska): Buried radionuclides from Cold War experiments (O’Neill 2015).

These cases align with Langer et al.’s (2023, p. 2) finding that thawing permafrost “destabilizes foundations and containment structures,” raising disturbing questions about the long-term security of nuclear waste solutions, especially in a world where institutional knowledge and maintenance will disappear.

Health Catastrophe for Survivors

For those who survive the initial collapse of civilization, the health impacts of widespread radioactive contamination would represent a slow-motion extinction event. Acute radiation exposure causes horrific suffering – doses of 5 sieverts (Sv) lead to death within weeks through destruction of the bone marrow and intestinal lining (WHO, 2023). But the greater threat may come from chronic low-dose exposure (0.1 Sv/year) that elevates lifetime cancer risk by 5-10% per sievert while also causing cardiovascular disease, cataracts, and cognitive impairment.

New research reveals that radiation exposure synergizes dangerously with other pollutants that will persist in a post-collapse world. A landmark 2025 Lancet Planetary Health study found that combined exposure to radiation, PFAS, and nanoplastics causes 42-58% greater DNA damage in human cells compared to radiation alone (Zhang et al., 2025). The same study showed a 40% reduction in lymphocyte counts under these combined exposures – a finding with dire implications for survivors who would need functioning immune systems to survive in a pathogen-rich post-collapse environment.

The generational impacts may be even more disturbing. Studies of wildlife in Chernobyl’s exclusion zone show that chronic radiation exposure leads to evolutionary adaptation at a terrible cost – Chernobyl wolves exhibit 15% shorter telomeres and 3 times higher cancer rates than control populations (Science, 2024). While Murase et al. (2019) observed a nationwide increase in neonatal complex congenital heart defect (CHD) surgeries following the Fukushima nuclear accident, Gu et al. (2021) suggest that maternal stress—a common disaster-related factor—may contribute to CHD risk, highlighting the challenge of isolating radiation as a direct cause amid confounding psychosocial stressors. You will have to draw your own conclusions.

Quantifying the Threat: The Scale of Our Nuclear Legacy

The full scope of humanity’s radioactive legacy is difficult to comprehend:

392,000 tons of spent fuel (a 7.8% increase since 2023) sits in temporary storage at reactor sites worldwide (IAEA, 2025)
33 billion curies of long-lived radioactivity, contained within the world’s 392,000 metric tons of high-level nuclear waste, include enough plutonium-239 to fabricate 44,000 nuclear weapons (based on the 55 grams used in Hiroshima’s device) (International Panel on Fissile Materials, 2023). This toxic legacy grows by 70,000 metric tons per decade as permanent disposal may never come (IAEA, 2025).
4,200 orphaned radioactive sources—a 14% rise since 2021—are now recorded in high-risk medical and industrial sites, with gaps in security enabling potential theft (IAEA, 2023).
1 operational floating reactor (Russia’s Akademik Lomonosov) with 4 more planned, creating new risks in vulnerable Arctic and coastal zones (Rosatom, 2025).

Perhaps most sobering is the timescale of the threat. Plutonium-239, with its 24,100-year half-life, will remain lethally radioactive for 240,000 years – longer than Homo sapiens has existed as a species. This means our nuclear legacy could outlast not just our civilization, but potentially our entire species.

Conclusion: The Millennial-Scale Consequences of Nuclear Hubris

The uncomfortable truth revealed by recent research is that nuclear technology represents a Faustian bargain made without full consideration of its millennial-scale consequences. Floating reactors, decaying sarcophagi, and synergistic health threats underscore nuclear energy’s fundamental incompatibility with a destabilizing world. Even if humanity were to magically mitigate climate change and preserve biodiversity, our nuclear legacy – 240,000 years of plutonium toxicity and counting – remains as a permanent scar on the planet.

In the bottleneck scenario, where civilization fragments and knowledge is lost, these nuclear time bombs will continue ticking. The survivors may find their refuge zones becoming death traps as reactors melt down and waste storage fails. Our radioactive sins, committed in the brief atomic age, could ultimately become the epitaph for our species, a warning to any future intelligent life about the dangers of technological hubris without long-term responsibility.

The Collapse of the AMOC: A Planetary Crisis Accelerating

The Atlantic Meridional Overturning Circulation (AMOC), a critical artery of Earth’s climate system, now stands on the brink of collapse. New research confirms that its failure would not merely disrupt weather patterns but unravel the delicate balance of global ecosystems, economies, and geopolitical stability, locking humanity into a future of cascading crises.

The AMOC’s Vital Role in Earth’s Climate

The AMOC functions as a global conveyor belt, redistributing heat and nutrients across the oceans. Driven by temperature and salinity differences, warm surface waters flow northward from the tropics, releasing heat to the atmosphere in the North Atlantic. As this water cools and becomes denser, it sinks to the deep ocean and returns southward, completing the cycle (Rahmstorf, 2006). This process moderates Europe’s climate, transports oxygen to deep-sea ecosystems, and fuels nutrient upwelling—the rise of cold, nutrient-rich water that sustains marine food webs. A healthy AMOC also sequesters carbon dioxide in the deep ocean and stabilizes atmospheric jet streams, which govern weather patterns like the North Atlantic storm track (Smeed et al., 2014).

Accelerated Warming and Aerosol Forcing: A New Paradigm

Recent work by Hansen et al. (2025) reveals that global warming has accelerated due to a “double whammy” of reduced aerosol cooling and underestimated climate sensitivity. The 2020 International Maritime Organization (IMO) restrictions on ship sulfur emissions, intended to improve air quality, reduced aerosol pollution by ~80% in key regions, removing a critical cooling mask and adding 0.5 W/m² of forcing globally. This reduction, combined with greenhouse gas-driven warming, caused a 0.4°C temperature spike in 2023–2024, breaching the 1.5°C threshold. Hansen’s analysis shows that IPCC models underestimate aerosol cooling by 50–100%, implying equilibrium climate sensitivity could exceed 4.5°C for doubled CO₂—far above the IPCC’s 3°C best estimate.

Biospheric and Oceanic Collapse: Accelerating Warming and Tipping Points

A collapsing AMOC would unravel marine and terrestrial ecosystems while accelerating global warming through feedback loops. In the oceans, the shutdown of nutrient upwelling, a process critical to phytoplankton growth, would starve marine food chains, collapsing fish populations by 40–60% in the North Atlantic by 2100. Simultaneously, warmer, stagnant tropical waters would expand oxygen-depleted “dead zones,” suffocating coral reefs and pelagic species. On land, the abrupt cooling of northern latitudes would devastate boreal forests, while tropical ecosystems like the Amazon face intensified droughts, pushing them toward irreversible dieback and releasing 90–140 gigatons of stored carbon. These biospheric shocks would compound warming: reduced ocean carbon uptake and vegetation loss could add 0.3–0.5°C to global temperatures by 2100, independent of emissions. Worse, the AMOC’s collapse could trigger interconnected tipping points. Greenland’s ice sheet, destabilized by meltwater from AMOC-driven freshening, risks irreversible disintegration, while Southern Ocean warming accelerates Antarctic ice loss, raising sea levels by 2.5 meters by 2100. Arctic permafrost, thawing 5–10% faster due to disrupted atmospheric circulation, would release methane, a greenhouse gas 80x more potent than CO₂, over decades. Together, these feedbacks could lock Earth into a “Hothouse” trajectory, far exceeding current warming projections.

Unseen Feedback Loops and Accelerated AMOC Collapse (2025 Update)

Groundbreaking 2024–2025 research exposes feedback mechanisms advancing faster than anticipated, demanding urgent recalibration of climate policies and collapse timelines.

1. Methane Wildcards: New Findings Could Reshape Projections:

(a) Subsea Methane Hydrates and Meltwater Discharge

East Siberian Arctic Shelf (ESAS): Beneath the icy silence of Antarctica, scientists have uncovered a hidden menace—towering columns of methane gas, some stretching 700 meters long, rising like ghostly chimneys from the seafloor. During a recent Spanish expedition aboard the Sarmiento de Gamboa, researchers observed these eerie plumes escaping from mud volcanoes and fractures in the Pacific margin of the Antarctic Peninsula, one of Earth’s fastest-warming regions (The Maritime Executive 2025). The methane, trapped for millennia as hydrate deposits—a crystalline mix of water and gas formed under pressure—is now destabilizing, hinting at a climate threat long feared but poorly understood. Current projections ignore Antarctic methane emissions and recent observations of such massive methane plumes does not bode well for other areas like the East Antarctic Ice Sheet (EAIS), a larger, older, and understudied region harboring vastly larger methane reserves.
AMOC Impact from Meltwater Discharge: Two recent studies indicate Greenland’s ice loss is entering a crisis phase, driven by a dangerous synergy of accelerating ice dynamics and year-round subglacial meltwater discharge. The first study (Chudley et al., 2025) exposes a 25.3% surge in crevasse volumes at rapidly flowing marine-terminating glaciers since 2016, directly linking ice sheet acceleration to destabilizing feedbacks: crevasses act as highways for meltwater, weaken ice structure, and amplify calving—effectively turning Greenland’s margins into crumbling, high-discharge zones. The second study (Hansen et al., 2025) delivers a bombshell: winter subglacial meltwater, previously dismissed as negligible, is now confirmed to seep into fjords year-round. This hidden meltwater, generated by frictional heating and geothermal energy, upwells warm Atlantic water to gnaw at glacier fronts while stockpiling nutrients for explosive spring algal blooms. Together, these findings reveal a double blow: ice sheets are disintegrating faster from below due to relentless meltwater discharge, even in winter, while surface acceleration tears them apart from above. Current climate models, which ignore these cascading mechanisms, risk grossly underestimating Greenland’s meltwater hemorrhage. As warming intensifies, this dual assault threatens to unleash runaway ice loss, with dire implications for global sea-level rise and Arctic ecosystems. The message is clear: Greenland’s meltwater discharge is not just accelerating—it’s evolving into an unchecked, year-round crisis.

(b) Abrupt Permafrost Thaw

Thermokarst Emissions Acceleration: A new study (Freitas et al. 2025) reveals that deep Arctic lake sediments, previously overlooked, are significant sources of greenhouse gases with profound climate implications. By incubating a 20-meter sediment core from Alaska’s Goldstream Lake, researchers found that anaerobic decomposition in thawed permafrost—particularly in ancient Yedoma and underlying fluvial deposits—produces methane and CO₂ at rates comparable to or exceeding aerobic processes, especially under warming temperatures. Crucially, anaerobic emissions at 10–20°C had double the global warming potential of aerobic emissions, challenging the assumption that shallow, oxygenated layers dominate carbon release. These findings suggest current climate models vastly underestimate the permafrost carbon feedback by neglecting deep sediment contributions. Wang et al. (2024) expose a climate time bomb in the Tibetan Plateau’s thawing permafrost: collapsing soils release 5.5 times more CO₂ under warming than stable ground, driven by microbial armies adapted to devour degraded organic matter. This explosive emissions surge, tied to thermokarst formation, threatens to double permafrost carbon losses, turbocharging global warming and demanding immediate action to defuse one of Earth’s most dangerous feedback loops.

2. Cloud-Ocean-Land Thresholds: The 2023 global temperature surge to nearly 1.5°C above pre-industrial levels—exceeding prior records by 0.17°C—was amplified by a record-low planetary albedo driven primarily by declining low-cloud cover over northern mid-latitudes and tropical oceans, according to satellite and reanalysis data, bridging a 0.2°C gap unexplained by anthropogenic warming or El Niño alone (Goessling et al. 2024). This albedo reduction, part of a multi-decadal trend, highlights uncertainties around contributions from internal variability, aerosol reductions, or emergent cloud feedbacks. AMOC Link: Cloud loss over the subtropical Atlantic raises sea temperatures, disrupting northward heat transport.

Ocean and Land Carbon Sink Decline

Ocean Saturation: The ocean, Earth’s silent climate ally, is faltering. Müller et al. (2023) reveal that between 1994 and 2014, it absorbed a staggering 29 billion tons of human-emitted carbon per decade—but its power to offset our pollution is slipping. By the 2000s, its efficiency had dropped 15% as rising CO₂ overwhelmed its chemistry and currents shifted, with the North Atlantic’s deep-water engine sputtering while southern waters churned faster. This alarming trend, uncovered through global ocean data analysis, signals a critical vulnerability: the seas are struggling to keep pace with humanity’s carbon footprint. Even more unsettling, gaps between ocean storage and surface measurements hint at rogue carbon leaks, turning the ocean from a steady sink into a climate wildcard.
Land Saturation: Curran and Curran (2025) found that natural systems like forests and soil, which absorb CO₂ from the air, are getting weaker at sequestering carbon. Their study, using data from Hawaii’s Mauna Loa Observatory, shows that since 2008, the amount of CO₂ absorbed during Northern Hemisphere summers has been dropping by about 0.25% each year. This decline—caused by wildfires, droughts, and thawing frozen ground—is making CO₂ levels in the atmosphere rise faster than before. For example, without this weakening absorption, the yearly increase in CO₂ would be 1.9 parts per million (ppm) instead of the current 2.5 ppm. The authors warn that global emissions must now fall by 0.3% yearly just to cancel out this lost natural absorption.

3. Revised AMOC Collapse Timeline Estimates

Threshold	Hansen (2025)	2025 Revised Timeline	Key Drivers
2°C Global Warming	2045	2035–2040	Methane surges, albedo loss
3°C Global Warming	2060–2070	2042–2048	Cloud loss, ocean sink failure
AMOC Collapse	2050–2070	2038–2045	Synergistic freshwater + warming

Key Revisions:

AMOC Collapse by 2045: Greenland meltwater and an AMOC slowdown make collapse possible within two decades under SSP5-8.5.
Regional Deadlines: Central North America faces 2°C by or before 2040 (Barnes et al, 2025) due to soil moisture-cloud feedbacks. Dry soils reduce evaporative cooling, increasing surface temperatures. Studies show regions like the U.S. Great Plains are hotspots for this feedback, where soil drying can intensify heatwaves by 1–3°C (Maraun et al. 2025). Low soil moisture may suppress cloud formation, allowing more solar radiation to reach the ground. Model simulations suggest this could add ~0.5°C to regional warming in semi-arid zones. Earth’s freshwater reserves are vanishing at a pace that eclipses polar ice melt, warns Seo et al. (2025). Between 2000 and 2002 alone, soil moisture—a critical buffer for ecosystems and agriculture—plummeted by 1,614 gigatonnes, nearly double Greenland’s ice loss during the same period. Satellite data, sea level spikes (~4.4 mm), and even Earth’s wobble (~45 cm pole shift) all point to a planet hemorrhaging water, driven by relentless droughts and unyielding evaporation. By 2021, recovery remained elusive, with projections suggesting this hydrological freefall is irreversible under current warming trends. The study paints a stark picture: human-driven climate change isn’t just melting ice—it’s draining the continents dry.

Regional Cooling, Global Warming, and Ecosystem Collapse

A collapse of the AMOC would plunge northern Europe and the North Atlantic into abrupt cooling, 3–5°C within decades, while accelerating warming across the tropics and Southern Hemisphere. This divergence would mask regional cooling in the north but amplify extremes elsewhere. The Southern Ocean, for instance, could warm 2–3 times faster than the global average, destabilizing Antarctic ice shelves and krill populations vital to marine ecosystems. Meanwhile, the North Atlantic’s marine food webs face ruin: a 2025 Nature study projects a 40–60% collapse in phytoplankton blooms by 2100, decimating fisheries that sustain millions. On land, the Amazon rainforest, already ailing from drought, could lose 30–40% of its biomass by 2070, releasing vast carbon stores and accelerating global warming.

Human Migration and the Fracturing of Geopolitical Order

The human toll of AMOC collapse would be catastrophic. A 2025 World Bank report warns of 200–300 million climate migrants by 2050, driven by drowned coastlines, failed harvests, and desertification. Northern Europe’s cooling could displace populations southward, while the Sahel faces existential drought, inflaming regional conflicts over dwindling water and arable land. Competition over Arctic resources, intensified by ice melt and new shipping routes, is already triggering militarization by Russia and NATO states. In the U.S. Northeast, 50–100 cm of sea-level rise by 2100, far exceeding prior estimates, threatens to displace 10 million people, overwhelming disaster response systems and sparking interstate strife.

Economic Freefall and Insurance Market Collapse

The global economy would reel under compound shocks. Northern Europe’s agricultural output could drop by €150–200 billion/year by 2040 due to shortened growing seasons, while Mediterranean droughts cripple olive and wine production. Coastal cities worldwide, from New York to Dhaka, face $1–2 trillion/year in flood damages by 2050. Insurance markets, a pillar of economic stability, are buckling: Lloyd’s of London predicts 30–50% premium hikes by 2030, with coastal properties becoming “uninsurable” within a decade. These losses would deepen global inequality, as low-income nations, least responsible for emissions, bear the brunt of crop failures and displacement.

Tipping Point Cascades: From Greenland to the Amazon

The AMOC’s collapse would not occur in isolation. It risks triggering a domino effect across Earth’s climate system:

Greenland Ice Sheet: Meltwater from Greenland, a key driver of AMOC weakening, could push the ice sheet past its tipping point, locking in 7 meters of long-term sea-level rise.
Amazon Dieback: Concurrent droughts and warming could push the Amazon past its tipping point by 2035–2040, releasing 90–140 gigatons of carbon—equivalent to a decade of global emissions.
West Antarctic Ice Sheet (WAIS): Southern Ocean warming would accelerate WAIS disintegration, potentially doubling sea-level rise projections to 2.5 meters by 2100.
Permafrost Feedback: Arctic permafrost thaw, exacerbated by AMOC-driven cooling-warming disparities, could release 5–10% more methane by 2040, a potent greenhouse gas.

Hansen et al. (2025) emphasize that these feedbacks are mutually reinforcing. For example, AMOC-driven Southern Ocean warming could destabilize WAIS within decades, while permafrost thaw adds 0.1°C to global warming by 2040—both excluded from IPCC’s “likely” ranges. Their analysis suggests a 40% probability of passing multiple tipping points by 2040 under current policies.

Conclusion: A Fork in the Road

The AMOC’s collapse would not “pause” global warming but redistribute its effects geographically. Northern Europe and the North Atlantic might experience temporary cooling, masking global trends locally, while the tropics and Southern Hemisphere warm at accelerated rates. Feedbacks like reduced oceanic carbon uptake and permafrost thaw would amplify long-term warming, creating a more uneven and complex climate response. Regional disruptions, from collapsing fisheries to intensified droughts, would escalate even as global temperatures continue to rise.

The AMOC’s potential collapse represents a planetary emergency, a “threat multiplier” that would fracture ecosystems, economies, and geopolitical order. While regional cooling might offer a deceptive respite in the North Atlantic, the broader consequences—runaway southern warming, mass migration, and interconnected tipping points—would dominate humanity’s trajectory. The window to prevent collapse is narrowing: the recovery, once lost, would take millennia.

Hansen et al. (2025) advocate for immediate, radical policy shifts: a global carbon fee-and-dividend system to phase out fossil fuels, coupled with investments in modern nuclear energy and solar radiation modification (SRM) research as a temporary buffer. They stress that current IPCC scenarios rely on implausible carbon capture assumptions and ignore aerosol forcing revisions, putting the 2°C target out of reach without SRM. However, they caution that SRM alone cannot substitute for emissions cuts—delayed action risks locking in AMOC collapse and meters of sea-level rise by 2100.

Policy Imperatives: 2025 Urgencies

MethaneSAT-2 Deployment: Launch AI-equipped satellites to track subsea and permafrost emissions in real time.
Stratospheric Aerosol Injection (SAI): Fast-track trials to offset cloud loss (e.g., SCoPEx Phase II).
Ocean Alkalinity Enhancement: Scale up carbonate addition to preserve CO₂ uptake.

Immediate emissions cuts, global cooperation on refugee resettlement, and investments in climate resilience are non-negotiable. The alternative is a world unrecognizable—a destabilized Earth system with diminishing room for human agency.

Safe Havens? The Myth of Escape

While no region would remain entirely unaffected by an AMOC collapse, certain areas may offer relative safety due to geographic, climatic, or geopolitical advantages. New Zealand and Tasmania are often cited as refuges due to their isolation, temperate climates, and lower exposure to extreme droughts or sea-level rise compared to low-lying tropical regions. Their southern latitudes might buffer against the worst of Northern Hemisphere cooling and tropical heating, though accelerated Southern Ocean warming could disrupt fisheries and rainfall patterns. Inland elevated regions like the Rocky Mountains (Canada/U.S.) or the Andes (South America) could avoid coastal flooding while benefiting from colder temperatures offsetting global warming. Scandinavia, despite facing abrupt cooling, has resilient infrastructure, freshwater resources, and low population density, which may help manage agricultural shifts. However, these regions would face challenges: mass migration pressures, disrupted global trade, and potential conflicts over resources like arable land and water. Even “safe” zones would need to adapt rapidly to erratic weather, biodiversity loss, and societal instability. Ultimately, survivability hinges less on geography and more on equitable governance, adaptive capacity, and global cooperation to mitigate cascading crises.

Post Script Notes

Someone on Reddit questioned my essay’s findings by posting a study, published in January of this year, which came to a very different conclusion about an AMOC collapse.

After analyzing their posted study, severe limitations and shortcomings were found in it.

While Terhaar et al. (2025) provide valuable insights into historical AMOC variability, their conclusions are constrained by outdated CMIP6 assumptions and a narrow focus on heat flux correlations. My essay’s integration of non-linear feedbacks, post-2020 observations, and policy-critical timelines offers a more accurate and urgent assessment of AMOC collapse risks. The Terhaar study’s dismissal of proxy-based reconstructions and tipping point cascades reflects a methodological conservatism that underestimates the compounding crises outlined in my essay.

The scientific studies and findings, supporting my essay’s multi-disciplinary, forward-looking approach, capture the accelerating planetary emergency better than Terhaar’s retrospective, model-limited analysis.

Here are the details:

Key Differences in Approach and Limitations of Terhaar et al. (2025)

Reliance on CMIP6 Models and Air-Sea Heat FluxesTerhaar’s study uses 24 CMIP6 models to argue that air-sea heat flux anomalies (not SST proxies) better reconstruct AMOC variability. They conclude that the AMOC at 26.5°N shows no significant decline from 1963–2017, attributing past variability to natural oscillations.
- Overlooked:
  - Accelerating feedbacks post-2017 (e.g., Greenland/Antarctic meltwater acceleration, methane surges) are excluded. Their analysis ends in 2017, missing critical post-2020 observations of ice sheet destabilization and freshwater forcing.
  - Non-linear tipping points: The study assumes linear relationships between heat fluxes and AMOC strength, ignoring threshold-driven collapses (e.g., freshwater hosing from Greenland, permafrost methane).
Dismissal of Proxy ReliabilityTerhaar critiques SST-based proxies (e.g., Caesar et al., 2018) as unreliable, arguing that SPG SST anomalies are confounded by atmospheric variability.
- Overlooked:
  - Multi-proxy synthesis: My essay integrates diverse proxies (methane hydrates, oxygen depletion, Amazon dieback) to capture interconnected Earth system feedbacks, not just SST.
  - Emergent constraints: Terhaar dismisses emergent constraints from CMIP5 but does not account for revised aerosol forcing and climate sensitivity (Hansen et al., 2025) that amplify AMOC collapse risks in newer models.
Limited Treatment of Anthropogenic ForcingThe study attributes AMOC variability to natural heat flux oscillations and downplays human-driven forcings. For example, they note aerosol reductions post-2020 but do not quantify their impact on AMOC freshening.
- Overlooked:
  - Aerosol “double whammy”: My essay highlights Hansen et al.’s (2025) finding that reduced sulfur emissions (post-IMO 2020 regulations) removed a critical cooling mask, accelerating warming and AMOC destabilization.
  - Methane feedbacks: Terhaar’s analysis excludes subsea methane hydrate destabilization (Semiletov et al., 2024) and permafrost thaw (Turetsky et al., 2025), which accelerate freshwater input and reduce ocean carbon uptake.
Ignored Tipping Point CascadesTerhaar focuses on historical AMOC variability but does not model future interactions with Greenland ice loss, Amazon dieback, or Southern Ocean warming.
- Overlooked:
  - Interconnected tipping points: My essay emphasizes that AMOC collapse would trigger Greenland disintegration (+7 m sea-level rise), permafrost methane release, and Antarctic ice loss—feedbacks excluded from CMIP6’s equilibrium simulations.
  - Reduced carbon sink capacity: Terhaar’s heat budget analysis does not account for declining ocean carbon uptake (Boers et al., 2024) or vegetation loss, which add 0.3–0.5°C to warming by 2100.

Why My Essay Is More Accurate

Holistic Earth System PerspectiveIntegrates methane hydrates, cloud feedbacks, and ice sheet dynamics—factors excluded from Terhaar’s CMIP6-based analysis. These feedbacks compress AMOC collapse timelines to 2038–2045 under SSP5-8.5.
Policy-Relevant UrgencyHighlights accelerated warming post-2023 (0.4°C spike from aerosol reductions) and the need for solar radiation modification (SRM) research—issues absent in Terhaar’s study.
Observational ConsistencyAligns with recent observations:
- - RAPID array data: Shows AMOC at its weakest in 1,600 years (Caesar et al., 2021).
  - Greenland meltwater: Now 360 Gt/year, double 1990s rates (Ditlevsen et al., 2024).

If I was wrong, I would fully admit it; but the facts state otherwise.

Agriculture in the Crosshairs: Breadbasket Collapse at 2°C and 3°C

The stability of global food systems hinges on a handful of critical “breadbasket” regions—the U.S. Midwest, Canada’s Prairie Provinces, the Indo-Gangetic Plain, and Mediterranean Europe. These regions, responsible for over 60% of global wheat, corn, and soybean exports, face existential threats even at 2°C of warming. By 3°C, their agricultural systems fracture irreparably, triggering cascading famines, market collapses, and mass migration. Below is a detailed analysis of how warming destabilizes these regions, with a focus on North America and Europe.

The Road to 2°C and Beyond: The Unraveling Begins (2030–2040)

U.S. Midwest: From Corn Belt to Dust Belt

At 2°C (2030–2040):

By 2035, global temperatures breach 2°C above pre-industrial levels. The world’s breadbaskets—regions that once fed billions—begin to fracture under heatwaves, droughts, and pestilence. In the U.S. Midwest, the Corn Belt’s golden fields now resemble a cracked mosaic. Compound heat-drought events, five to six times more frequent than in the 2000s, scorch maize and soybeans. Pollination fails as temperatures exceed 30°C (86°F) for weeks on end, causing corn ears to abort kernels en masse. Farmers who once harvested 200 bushels per acre now scrape together 80. The Ogallala Aquifer, lifeline of Great Plains irrigation, is 70% depleted. The 2020s “megadrought” becomes the new normal, with summer soil moisture dropping 40%. In Kansas, water rationing forces farmers to prioritize almonds over corn, a crop now genetically edited for drought tolerance but still faltering under 45°C (113°F) heat. CRISPR-edited maize, hailed as a savior in 2024 USDA-ARS trials, shows modest gains—15% higher yields—but only under moderate stress. Under extreme drought, even engineered crops wither. Corn rootworm and soybean aphids expand northward, resistant to pesticides. Aflatoxin—a carcinogenic mold—contaminates 25% of stored grain due to humid nights.

We were forewarned of these events from scientific research in 2014 and more recently:

Modeling by Leng et al. (2024) reveals that compound heat-drought events—now three times more frequent than in 2000. To project their frequency and crop loss in 2035, we must consider:

1. 1. 1. Current Trajectory:
      - By 2024, warming (~1.5°C) has tripled the frequency of these events.
      - Under current emissions policies (SSP2-4.5), global temperatures are projected to reach ~2.0°C by 2035.
    2. Nonlinear Acceleration:
      - Compound heat-drought events do not scale linearly with warming. Each 0.5°C increase disproportionately amplifies their frequency and severity due to:
        
        Heatwave intensification (exponential rise in extreme temperatures).
        
        Soil moisture feedbacks (drier soils worsen drought conditions).
      - Studies (e.g., IPCC AR6) show that at 2°C, the frequency of concurrent heat-drought events increases 5–7× over pre-industrial baselines.
    3. 2035 Projection:
      - By 2035 (~2°C), compound heat-drought events in breadbaskets like the U.S. Midwest would become 5–6× more frequent than in 2000 (or 1.6–2× more frequent than in 2024).
      - This means a region experiencing 1 severe event per decade in 2000 would face 5–6 events per decade by 2035.

Key Implications

- - - - Crop Losses: At 5–6× frequency, maize yields in the Midwest could decline 45–60%

The Global Water Security Institute (2023) warned that 70% of the Ogallala Aquifer—critical for irrigating 30% of U.S. cropland—will be irreversibly depleted by 2040.

Pests and Pathogens

- - - - Deutsch et al. (2018)
        “Increase in Crop Losses to Insect Pests in a Warming Climate” (Science).
        Warns that global warming boosts insect metabolism and reproduction, increasing crop losses by 10–25% per degree Celsius.
      - EPA (2021)
        “Aflatoxin Contamination Risk Under Climate Change”.
        Links rising nighttime humidity to aflatoxin outbreaks in the Midwest, contaminating 25% of stored grain by 2°C.

At 3°C (2045-2055):

By 2055, Earth’s temperature climbs to 3°C. The Midwest becomes a post-agricultural wasteland. Dust storms strip topsoil, reducing yields by 90%. The Midwest faces Dust Bowl 2.0, with topsoil erosion rates tripling as 100-year storms strip exposed fields. Autonomous harvesters ($500K each) replace human laborers, who flee lethal wet-bulb temperatures exceeding 32°C (90°F) for 30 days/year. The Entomology Society of America (2024) predicts CRISPR-edited pest-resistant crops will spur rapid insect evolution, requiring costly new gene edits every 5–7 years. By 2050, aflatoxin contamination renders 40% of U.S. corn unfit for human consumption.

Southern Canada: The Prairies Under Siege

At 2°C (2030–2040):

Canada’s Prairie Provinces, once a climate refuge, now grapple with erratic rainfall and northward pest invasions. The Agriculture and Agri-Food Canada (2024) reports that wheat yields in Manitoba—the new Saskatchewan—drop 25% due to poor soil structure in thawed permafrost zones. Hailstorms, amplified by atmospheric instability, decimate 10% of crops annually, while neonicotinoid use triples to combat invasive grasshoppers, collapsing wild bee populations.

At 3°C (2045–2055):

Boreal wildfires, fueled by thawing peatlands (Turetsky et al., 2019), blanket the Prairies in smoke, reducing photosynthesis and slashing wheat protein content by 30%. Methane bursts from Alberta’s permafrost force farmers to don gas masks during planting. Geopolitical tensions flare as the U.S. invokes revised NORAD agreements to seize Canadian grain reserves, sparking protests in Winnipeg.

Mediterranean Europe: From Olive Groves to Wastelands

At 2°C (2030–2040):

The EU Joint Research Centre (2024) identifies 2.2°C as the tipping point for irreversible olive collapse in Spain and Italy, driven by Xylella fastidiosa outbreaks and aquifer salinization. Southern Spain loses 50% of arable land to desertification, while Portugal’s farmers dynamite Spanish dams to divert the Tagus River’s dwindling flow. Coastal aquifers in Sicily turn brackish, poisoning vineyards and citrus groves.

At 3°C (2045-2055):

Southern Europe crosses into irreversibility. Andalusia hits 50°C (122°F), its olive presses abandoned to Saharan dust. Synthetic “EuroFlavor” gels, engineered to mimic extinct olives and grapes, dominate supermarkets. The World Resources Institute (2024) documents cross-border water wars as 20 million Southern Europeans migrate north, overwhelming Germany’s refugee camps. Immigrants are met with drone patrols and far-right militias.

Who Eats at 3°C? The Hierarchy of Survival

The Elites (0.1%): Silicon Valley billionaires, Gulf royalty, and politburo members retreat to fortified enclaves. Subterranean cities produce lab-grown “heirloom” vegetables and CRISPR salmon to sustain the ultra wealthy. They hoard 3D-printed meat and Arctic-grown barley. Private armies guard desalination plants. Climate Apartheid: Biometric IDs grant access to fortified zones.
The Professional Class (10%): Scientists, engineers, doctors/nurses, and computer technicians barter skills for rations.
The Majority (90%): Billions subsist on insect farms, feral rats, and ration packs.

Supply Chains: From Fragmentation to Anarchy

At 2°C:

Export Bans: The U.S. and EU halt grain exports, prioritizing domestic stability. Egypt, dependent on imports, collapses into famine. [Chatham House (2024) Report – “Climate Nationalism: Food Export Bans in a 2°C World”]
Algorithmic Exploitation: AI traders (IFPRI, 2023) trigger speculative bubbles, spiking rice prices 300% during Bangladesh floods.
Last-Chance Logistics: Solar-powered drones deliver CRISPR seeds to Canadian Prairies, but 40% are intercepted by warlords.

At 3°C:

Panama Canal Collapse: Superstorms cripple shipping lanes. Chinese drones bomb Australian grain freighters in contested waters.
Black Markets: CRISPR seeds smuggle through Balkan routes; lithium and rare earth minerals, powering elite technology, are supplied to the highest bidder.
Localized Warlordism: Ex-military commanders control Midwest silos, trading grain for loyalty.

Pollinators: The Silent Collapse

By 2°C, wild bees vanish. Neonicotinoids, CRISPR pollen, and habitat loss decimate populations. The FAO’s 2023 Global Soil Health Report links soil carbon loss to pollinator decline—40% fewer flowers sustain remaining bees. By 3°C, robotic drones replace pollinators in elite greenhouses, while the masses rely on wind and luck. Almond orchards, once dependent on bees, collapse.

The Domino Effect on Global Markets

At 2°C:

The Chatham House (2024) simulates how U.S. and EU grain export bans would spike global prices by 400%, destabilizing 40+ food-import-dependent nations. Egypt’s bread subsidies collapse, reigniting Arab Spring-style protests, while hedge funds hoard grain futures. Algorithms, as exposed by the International Food Policy Research Institute (2023), exploit climate disasters for profit, triggering speculative frenzies.

At 3°C:

The European Commission Joint Research Centre (2021) models a 40% reduction in global grain trade as storms cripple the Panama Canal and China blockades Australian shipments.

The World Bank’s “Game Over” Threshold: 4°C

By 4°C (post-2065), the World Bank’s 2012 projections manifest:

Midwest: Corn yields drop 90%; abandoned silos dot salt flats.
Canada: Acidic boreal soils sustain only lichen.
Mediterranean: The region becomes a “zone of abandonment,” where governance and economy collapse under overlapping crises. Northern Europe survives as a fortress region, but only through authoritarian resource hoarding and exclusionary policies.

Schewe et al. (2014) warns of 90% yield declines in breadbaskets, while FAO’s 2023 Global Soil Health Report links extreme heat to 40% soil carbon loss, crippling nutrient retention.

Emerging Solutions—And Their Limits

MIT Climate-AI Lab (2024): Proposes autonomous vertical farms using perovskite solar cells to cut water use by 90%, but scaling requires $1 trillion and rare earth minerals.
European Green Deal (2024): Funds CRISPR-engineered barley for Saharan solar farms, yet yields lag 30% behind pre-collapse Mediterranean outputs.
CRISPR Limitations: Pest resistance lasts only 5–7 years before insects adapt (Entomology Society of America, 2024).

Hansen’s Scientific Prophecy Fulfilled

James Hansen’s 2025 paper, Global Warming Acceleration: Are the United Nations and the Public Well-Informed?, laid bare the mechanisms of doom. His warnings about albedo loss—the Earth’s dimming reflectivity due to melting ice and darkened oceans—proved prescient. By the 2040s, the loss of Arctic sea ice and soot-covered glaciers had reduced Earth’s albedo by 0.8%, adding the heat equivalent of 200 ppm CO₂ to the atmosphere. This accelerated warming, ignored by policymakers, pushed feedback loops into overdrive:

Permafrost Thaw: By 2050, Siberia’s permafrost emitted 4 gigatons of methane annually—equivalent to 1,000 coal plants.
AMOC Collapse: The Atlantic Ocean’s circulation system stalled in 2047, triggering famines in Europe and mega-droughts in the Amazon.
Cloud Feedback: Stratocumulus clouds over the Pacific thinned, unmasking an additional 0.8°C of warming by 2060.

Conclusion: A Narrowing Window

Recent 2023–2024 studies confirm that 2°C is a death sentence for global food systems. Yet humanity’s trajectory remains locked into 3°C by 2050. By 3°C, breadbasket collapse triggers geopolitical chaos and market failures that outpace technological fixes. The elites’ techno-feudalism offers no salvation—only a slower collapse. The only viable path is a global mobilization to:

Decarbonize immediately (net-zero by 2035).
Open-source CRISPR and green tech to all nations.
Restore soils and pollinators through agroecology.
Resilience (e.g., decentralized water harvesting)

Without this, the phrase “breadbasket” will join “glacier” and “coral reef” in the lexicon of extinction.

3–4°C Becomes the Gateway to a Post-Civilizational Dark Age

6th Mass Extinction, Albedo Loss, Amazon Die-Off, Antarctic Ice Melt, Anthropogenic Climate Disruption (ACD), Climate Change, Coral Die-Off, Dystopic Future, James Hansen, Megadrought, MegaFires, Sea Level Rise

James Hansen’s recent analysis paints a dire picture: 3°C by 2050 is not just plausible but probable due to underestimated feedbacks and political inertia. Crossing 2°C unleashes irreversible feedback loops that render 3°C unavoidable, even with rapid emissions cuts. The only hope is a wartime-scale mobilization to decarbonize, restore albedo, and prepare for a destabilized climate. Without this, Earth’s systems will push civilization beyond adaptation limits by mid-century.

Under current policies (SSP2-4.5), CO₂ likely reaches 500–550 ppm by 2050, but Hansen’s effective forcing (including feedbacks) pushes Earth’s energy imbalance closer to 600 ppm-equivalent—enough to trigger 3°C warming even before mid-century.

Current Emissions Trajectory

- CO₂ Levels (2024): ~425 ppm (pre-industrial: 280 ppm).
- Effective CO₂: ~557 ppm when factoring in albedo loss (+138 ppm equivalence).
- Annual Emissions: ~40 billion tons of CO₂/year, with no decline in fossil fuel use (oil/gas demand still rising).

Feedbacks Locking in 3°C

A. Ice Sheet Melt and Albedo Loss

- Greenland/Ice Sheets: Already losing 1.2 trillion tons/year, contributing to sea-level rise and reducing Earth’s reflectivity.
- By 2050: Ice-free Arctic summers darken oceans, adding +0.3–0.5 W/m² of absorbed solar energy (equal to ~50 ppm CO₂).
- Antarctica: Thwaites Glacier collapse accelerates, injecting freshwater into oceans, disrupting the AMOC (Atlantic circulation) by 2040–2050.

B. Permafrost Thaw

- Carbon Release: Arctic permafrost holds 1,400 gigatons of CO₂ and methane (twice atmospheric CO₂). At 2°C, thawing emits 50–100 gigatons by 2050, adding ~0.2–0.3°C to warming.
- Methane Bursts: Subsea permafrost in the East Siberian Arctic Shelf leaks methane—a greenhouse gas 84x more potent than CO₂ over 20 years.

C. Cloud Feedbacks

- Stratocumulus Clouds: Over tropical oceans, these reflective clouds thin or dissipate at ~1,200 ppm CO₂, adding +0.8°C globally.
- Earlier Impact: Hansen suggests this threshold could be crossed sooner due to combined CO₂ and albedo forcing.

Why 2°C Triggers “No Return”

At 2°C (likely 2030–2035 per Hansen):

- Greenland Tipping Point: Melt becomes unstoppable, committing to 7m sea-level rise over centuries.
- Amazon Dieback: 40–60% of rainforest transitions to savannah, releasing 90 billion tons of CO₂.
- Permafrost Carbon Bomb: Thawing becomes self-sustaining, emitting 10+ gigatons CO₂/year by 2050.

These feedbacks add ~0.5–1.0°C to warming by 2050, even if emissions stop.

Likelihood of 3°C by 2050

Factor	IPCC AR6 (2023)	Hansen et al. (2025)
Climate Sensitivity	3°C per CO₂ doubling	4.8°C per CO₂ doubling
Aerosol Cooling Loss	Partially modeled	Underestimated by ~1.0°C
2°C Threshold	~2040–2050	2030–2035
3°C by 2050	Low probability	High probability

Hansen’s Conclusion:

Current policies (SSP2-4.5) lead to 3°C by 2050 due to:

- Higher sensitivity (4.8°C vs. 3°C).
- Albedo loss equivalent to +138 ppm CO₂.
- Fast feedbacks (permafrost, ice melt) accelerating warming.

Regional Impacts at 3°C

- Heatwaves: 60+ days/year above 40°C (104°F) in Chicago, Paris, and Beijing.
- Food Collapse: 50–70% crop failures in breadbaskets like the U.S. Midwest and India.
- Water Wars: Colorado River and Nile Basin nations clash over dwindling resources.
- Mass Migration: 1–2 billion refugees from tropics and coasts.

Can We Avoid 3°C?

- Immediate Action Required:
- Phase out fossil fuels by 2040, not 2050.
- Scale carbon removal to 10+ gigatons/year (current capacity: 0.01 gigatons).
- Solar Geoengineering: Temporarily offset albedo loss via stratospheric aerosols (risky but possibly necessary).
- Current Reality: Policies remain aligned with 2.5–3.5°C by 2100, making 3°C by 2050 likely.

Conclusion

Hansen’s analysis paints a dire picture: 3°C by 2050 is not just plausible but probable due to underestimated feedbacks and political inertia. Crossing 2°C unleashes irreversible feedback loops that render 3°C unavoidable, even with rapid emissions cuts. The only hope is a wartime-scale mobilization to decarbonize, restore albedo, and prepare for catastrophic climate destabilization. Without this, Earth’s systems will push civilization beyond adaptation limits by mid-century.

At 3–4°C, Earth becomes a hostile planet where civilization persists only in fragmented, militarized enclaves. The transition would involve unimaginable suffering for billions, with the Global South bearing the brunt. However, humans are resilient—our species would survive, but the social, economic, and technological achievements of the past millennium would unravel.

Coastal megacities like Miami, Shanghai, and Mumbai lie half-submerged, abandoned to rising seas as governments prioritize inland fortress-cities. The tropics, once teeming with life, become uninhabitable dead zones where wet-bulb temperatures exceed 35°C for months on end, rendering outdoor labor fatal and driving billions northward. In regions like South Asia and the Sahel, collapsed monsoon cycles and dried-up rivers ignite water wars, while failed states fracture into warlord territories battling over dwindling aquifers and arable land.

Agriculture, the bedrock of civilization, buckles under heatwaves and soil depletion. Once-fertile breadbaskets—the U.S. Midwest, India’s Gangetic Plain, China’s North Plain—yield only dust and stunted crops, triggering famines that ripple across supply chains. Global food production plummets by half, leaving 2 billion people chronically malnourished. Oceans, acidified and starved of oxygen, lose their fisheries, collapsing protein sources for 3 billion coastal inhabitants. The global economy, stripped of stability, fractures into hyper-localized survival networks: underground hydroponic farms in abandoned warehouses, black-market water traders, and solar-powered enclaves guarded by drones.

Human society splinters along stark lines of privilege and desperation. Wealthy nations like Canada and Scandinavia fortify their borders with AI-patrolled walls, preserving pockets of climate-controlled normalcy for elites. Meanwhile, equatorial regions descend into chaos, where resource scarcity fuels epidemics, child mortality soars, and ancient cultural traditions vanish. Mass migrations—1 to 2 billion people fleeing heat, hunger, and conflict—overwhelm borders, sparking xenophobic violence and authoritarian crackdowns. Cities like Chicago and Berlin, struggling under heatwaves and infrastructure decay, ration electricity to a few hours a day, while their wealthy residents retreat into sealed, air-filtered high-rises.

Yet even in this unraveling world, glimmers of adaptation emerge. Polar regions and high-altitude zones—Siberia, Patagonia, the Tibetan Plateau—become lifeboats for humanity, their cooler climates hosting geoengineered forests and refugee megacities. Technologies like stratospheric aerosol injection temporarily cool the planet, buying time for carbon-sucking artificial trees and lab-grown meat factories. But these fixes are fragile, contingent on global cooperation that rarely materializes.

Civilization, in any recognizable form, survives only in fractured dystopian remnants. Governance shrinks to city-states and corporate fiefdoms, while democracy erodes under emergency decrees. Knowledge economies collapse, replaced by subsistence trades and barter systems. The arts and sciences stagnate, their progress halted by the daily scramble for survival. Humanity endures, but as a diminished species—a shadow of its former ingenuity, haunted by the loss of biodiversity, cultural heritage, and the stable climate that once nurtured its rise.

This future is not yet inevitable, but it looms as the trajectory of complacency. Hansen’s work warns that every delay in slashing emissions tightens the grip of feedback loops, sealing a fate where 3–4°C becomes the gateway to a post-civilizational dark age. The difference between survival and collapse hinges on this decade’s choices: rapid decarbonization, global equity, and a moral awakening to defend the fragile systems that sustain life. As Hansen warns: “Delay is denial.”

Analysis: How Soon Will Large Scale Collapse Happen

6th Mass Extinction, Albedo Loss, Amazon Die-Off, Antarctic Ice Melt, Anthropogenic Climate Disruption (ACD), Climate Change, Coral Die-Off, Insurance Industry Collapse, James Hansen, Megadrought, MegaFires, Sea Level Rise

James Hansen came out with a new study last month entitled, “Global Warming Has Accelerated: Are the United Nations and the Public Well-Informed?” I’m assuming the title is a rhetorical question since it is apparent to anyone with half a brain that we are currently living through a real-life Idiocracy timeline, i.e. look no further than the White House. Central to Hansen’s study is the loss of albedo. His paper explicitly accounts for the 0.5% albedo loss since 2010 and uses it as a core driver of his revised warming projections. Prior IPCC models underestimated or ignored albedo feedbacks. Here’s why Hansen’s findings are groundbreaking:

1. Hansen’s Inclusion of Albedo Loss

The albedo reduction is central to his analysis:

Quantified Impact: Hansen calculates the 0.5% albedo drop as equivalent to +138 ppm CO₂(raising effective forcing from 419 ppm to 557 ppm in 2024).
Climate Sensitivity: This forcing supports his revised equilibrium climate sensitivity (4.8°C per CO₂ doubling vs. IPCC’s 3°C).
Tipping Points: Albedo loss accelerates ice melt, which Hansen links to AMOC collapse by 2040–2050 and earlier sea-level rise.

2. Why It Changes Projections

Hansen’s albedo-driven adjustments explain why his warming timelines are far more urgent than the IPCC’s:

Factor	IPCC AR6 (Ignoring Albedo)	Hansen et al. (With Albedo)
Effective CO₂ (2024)	419 ppm	557 ppm (419 + 138 ppm albedo)
2°C Threshold	~2040–2050	2030–2035
Climate Sensitivity	3°C per CO₂ doubling	4.8°C per CO₂ doubling
AMOC Collapse Risk	“Low likelihood” this century	Likely by 2040–2050

Key Insight: The albedo loss effectively fast-forwards Earth’s climate to a higher-CO₂ state without actual CO₂ increases. This means:
- Warming observed today (1.5°C) reflects forcing akin to 557 ppm CO₂, not 419 ppm.
- Feedbacks (ice melt, permafrost thaw) are triggered earlier than IPCC models predict.

3. Why Other Models Missed This

Satellite Data Gap: Prior assessments lacked precise CERES satellite albedo measurements (2000–present), which Hansen’s team used to quantify the 0.5% drop.
Nonlinearity Ignored: IPCC models treat albedo as a linear feedback, but Hansen shows it’s accelerating (e.g., Arctic sea ice loss begets more ocean heat absorption).
Aerosol Masking: IPCC underestimated how pollution cuts (e.g., ship fuel regulations) would unmask warming. Hansen’s albedo loss includes this effect.

4. Policy Implications

Net-Zero Isn’t Enough: Even if CO₂ emissions stop today, the +1.7 W/m² albedo forcing (≈138 ppm CO₂) commits Earth to ~0.5°C additional warming by 2050.
Aerosol Phaseout Dilemma: Reducing fossil fuel aerosols (e.g., coal pollution) could unmask another 0.3–0.5°C by 2040.
Solar Geoengineering: Hansen argues for urgent research into temporary albedo restoration (e.g., stratospheric aerosols) to buy time for emissions cuts.

Hansen’s albedo analysis doesn’t just “update” projections—it rewrites them. By revealing that Earth’s energy imbalance is far worse than assumed, he shows that:

2°C is imminent (2030–2035), not mid-century.
3°C by 2050 is plausible under current policies.
The IPCC’s “safe” CO₂ thresholds (e.g., 350 ppm) are obsolete; we’re already in “dangerous” territory (effective 557 ppm).

Hansen’s findings reveal that Earth’s energy imbalance is far worse than assumed, with albedo loss acting as a hidden turbocharger for warming. Current policies, calibrated to IPCC models, are underestimating near-term risks by decades. To avoid 3°C by 2050, emissions must plummet twice as fast as Paris Agreement targets, paired with unprecedented carbon removal and adaptation efforts. Rapid decarbonization and negative emissions technologies are now non-negotiable to avoid existential risks to civilization.

Without radical action, 2°C by 2030–2035 locks in irreversible damage, including meters of sea-level rise, an ice-free Arctic (darkening oceans and amplifying warming), coral extinction, and ecosystem collapse. At 2°C, 40–60% of the Amazon transitions to savannah due to drought and fires. The Amazon flips from carbon sink to emitter, releasing 90B tons of CO₂. At 2°C, 99% of tropical coral reefs bleach and die, unable to adapt to acidic, hot waters. There will be a 90% decline in North Atlantic cod, tuna, and shellfish by 2050. There will be 1.2B climate refugees by 2050 (Institute for Economics & Peace), overwhelming global governance. In addition to the hundreds of gigatons of CO₂ and methane that will be released, equivalent to 150 years of human emissions, thawing permafrost will also destroy 70% of Arctic roads, pipelines, and cities by 2050.

At 2°C, Earth crosses into a “point of no return”: feedbacks like ice sheet melt and permafrost thaw become self-sustaining, locking in 3–4°C even if emissions stop. Civilization as we know it cannot adapt to this pace of change. 2°C is not a “safe” threshold but a gateway to irreversible collapse. Humanity’s window to act is closing by 2030.

Projections for Insurance Industry Collapse After Factoring in Hansen’s New Analysis

1. Key Changes from Albedo-Driven Warming

2°C Threshold: Now likely by 2030–2035 (vs. IPCC’s 2040–2050), escalating weather disasters 10–20 years earlier.
Extreme Event Costs: Insured losses could rise to ** $(u p f ro m$ 150B today).
Compound Risks: Concurrent disasters (e.g., hurricanes + wildfires + floods in the same year) become more frequent, overwhelming reinsurance capacity.

2. Revised Timelines for Insurance Market Failure

A. Regional Uninsurability

Timeline: 2030s–2040s (vs. prior 2040s–2050s).
- Coastal Zones: Miami, Mumbai, and Shanghai face premiums exceeding 15% of median income by 2035, triggering mass insurer withdrawals.
- Wildfire Regions: California, Australia, and Mediterranean Europe see 50% of properties uninsurable by 2040.

B. Systemic Liquidity Crisis

Timeline: 2040s (vs. prior 2050s).
- Reinsurance Collapse: Global reinsurance capital (~ $b eco m es in s u ff i c i e n t t o co v er **$ 1T+ annual losses** by 2040.
- Credit Downgrades: Major insurers (e.g., Allianz, AIG) face junk ratings as climate liabilities explode.

C. Sovereign Bailouts

Timeline: 2050s (vs. prior 2060s).
- NFIP-Style Programs: U.S. National Flood Insurance Program ($20B debt) collapses by 2045, requiring federal bailouts.
- Emerging Markets: Countries like Indonesia and Nigeria default on climate-linked debt as disaster costs exceed 10% of GDP.

3. Climate-Driven Triggers for Insurance Collapse

Risk Factor	Pre-Albedo Timeline	Post-Albedo Timeline	Impact
Coastal Uninsurability	2040s	2030s	Florida’s insurance market collapses by 2035 (vs. 2040).
Wildfire Premiums 2x	2050	2035	California premiums hit $10K/year for average homes.
Global Reinsurance Gap	2060	2045	Reinsurers cover only 30% of losses, vs. 70% today.

4. Why Albedo Loss Changes the Game

Faster Heat Buildup: Darker surfaces (oceans, soot-covered ice) absorb more solar energy, intensifying heatwaves, droughts, and storms.
Compound Events: Albedo loss amplifies feedbacks (e.g., Arctic warming → jet stream destabilization → prolonged droughts/floods), increasing correlated risks.
Economic Shock: Insurers face “climate stagflation”—rising premiums reduce coverage demand while claims surge, collapsing profit margins.

5. Mitigation vs. Reality

Adaptation Efforts: Parametric insurance and AI risk models may delay collapse in wealthy nations (e.g., EU, U.S.), but fail in tropics.
Government Backstops: Nationalization of insurance sectors (e.g., Australia’s cyclone pool) becomes inevitable by 2040, but strains public budgets.
Equity Crisis: Low-income households face de facto climate redlining, losing access to mortgages and insurance entirely.

6. Likelihood of Full Collapse

Partial Collapse (High Confidence): 30% of global markets uninsurable by 2040 (vs. 2050 previously).
Full Collapse (Still Low Probability): Requires 3°C+ warming by 2060, but albedo loss makes this trajectory more plausible.

Conclusion

Albedo loss advances insurance industry collapse by 10–15 years, with regional uninsurability beginning in the 2030s and systemic failures by the 2040s. The industry’s core business model—spreading risk across time and geography—fails in a world of concurrent, accelerating disasters. While wealthier economies may temporarily subsidize coverage, the global insurance system will fragment by mid-century, shifting climate costs directly to households and governments. Without radical emissions cuts and financial reforms, climate-driven economic collapse becomes unavoidable by 2060.

~~~~~~~~~

I have provided my readers with clear-eyed projections of what is to come in the near future. One of my readers was insisting that we would hit 3C of warming by 2032, but this is physically impossible for the following reasons:

Why 3°C by 2032 Is Impossible

Thermal inertia: Oceans absorb ~93% of excess heat, delaying atmospheric warming. Even with albedo loss, full equilibrium warming takes decades.
Feedback timescales: Major tipping points (e.g., Amazon collapse, methane clathrate destabilization) unfold over decades to centuries, not years.
Emissions reality: Fossil CO₂ emissions are rising (~1% annually), but atmospheric CO₂ growth is ~2.5 ppm/year. To hit 3°C by 2032, CO₂ would need to spike to ~600 ppm (currently 425 ppm)—a physically impossible 17.5 ppm/year rise. Even under RCP8.5 (a high-emissions pathway), warming by 2030 is projected at ~1.7–2.0°C in most studies. Hansen’s analysis aligns with this, emphasizing that 3°C by 2032 would require implausibly rapid forcing (e.g., sudden methane bursts or total collapse of Earth’s carbon sinks).

Nonetheless, the fact that we are facing 2C of warming very soon should be terrifying enough for everyone on the planet.

Preaching mindless consumption, the masses obey,
Pain and empathy drowned in dopamine’s sway.
Society transfixed by endless digital streams,
While landfills swell with discarded plastic dreams.

Earth screams warnings that no one will heed—
While we crown jesters and bury the seed.
Lips sewn shut, the truth is denied,
We parade in chains we’ve chosen with pride.

Our touch grows cold, our words sound contrived,
False promises leave us forever deprived.
Sadly we yield to each self-serving lie,
Though many know, they still choose to deny.

In ivory towers, privileged elite, devoid of shame,
Ignore the masses who suffer from flood, famine, and flame.
The decadent rich avert their jaded old eyes—
“Those fools chose their end,” they callously surmise

Wars rage on with destruction and death,
And Gaia gasps out her last dying breath.
We mined the veins and drained every well;
The Reaper now tolls fate’s final knell.

The seas will rise, and the streets will burn,
Yet still we ignore what we don’t want to learn.
The final minutes tick off death’s clock of doom—
Alas, we have built our own dark burial tomb.

Ticking Off The Checklist For Mass Extinction

Abrupt Climate Change, AMOC, Antarctic Ice Melt, Anthropocene Mass Extinction, Arctic Ice Melt, Atlantic Meridional Overturning Circulation, Blue Acceleration, Canfield Ocean, Capitalism, Carbon Dioxide, Climate Change, CO2, Cretaceous–Paleogene Extinction Event, Dr. Peter Ward, Fossil Fuel Dependency, Gerald Durrell, Great Acceleration, Gulf Stream, Hothouse Earth, Hydrogen Sulfide (H2S), IPCC, Jet Stream, K-T Extinction, Loss of Biodiversity, Megadrought, Methane, Micro-Plastic Pollution, Nate Hagens, Nicholas P. Money, Ocean Acidification, PETM Extinction Event, Sea Level Rise, Social Media Algorithms, Widespread Ocean Anoxia

Nate Hagens’ recent interview of Professor Peter Ward, entitled “Oceans – What’s the Worst that Can Happen?”, serves as a good overview of mankind’s destruction of the marine biosphere and our road to extinction. The title is a rather rhetorical question because very bad things have happened, are already happening, and even worse things are unavoidable and on the horizon despite hopes that humans will run out of ways to extract the dirtiest and most inaccessible fossil fuel deposits. We have seen how inextricably linked economic growth is to rising fossil fuel consumption, no matter the mounting disasters happening before our eyes and the steady stream of dire warnings issued from the scientific community. The most current of such warnings came from the UN last month, and it states that escalating synergies between disasters, economic vulnerabilities and ecosystem failures are increasing the risk of a “global collapse” scenario. Such a catastrophic scenario appears all but inevitable. Constricting fossil fuel consumption is like squeezing a balloon. If one country stops consumption, another takes up the slack. For example, efforts to cripple Russia’s fossil fuel exports for their unwarranted invasion of Ukraine don’t appear to be very effective since China and India have simply stepped in and increased their purchases. Rising oil prices have also more than offset a decline in Russia’s export volumes. Perhaps an unintended consequence of those higher energy prices will be the ripple effect through the economy, making food unaffordable for large swaths of the globe and destabilizing governments.

Getting back to the Peter Ward interview, the professor states matter of factly, “Every time we get into a car, it’s putting more of those CO2 particles into the atmosphere. And if this isn’t collective suicide by Homo sapiens, I don’t know what is.” Unfortunately for us, humans have created an unsustainable civilization supporting billions of people while at the same time destroying the very foundation upon which that system is dependent. Humans are by far outperforming the carbon-spewing volcanoes of past mass extinctions. Nicholas Money, renowned mycologist and author of many books, recently wrote:

Decades ago, Gerald Durrell, the famous conservationist, recognized that “the human race is in the position of a man sawing off the tree branch he is sitting on.” Thirty years after Durrell’s death, the human population has increased by 2 billion and the damage has intensified. The branch will snap now whether we keep sawing or not.

The timeline for extinctions is not known, but, sooner or later, the disappearing mammals will be joined by the other groups of animals. Almost everything will be leaving the metaphorical ark, creeping down the gangplank into oblivion. Millions of other species, seen and unseen, including plants, seaweeds, and fungi will be leaving, too. The tiniest of organisms will inherit the planet, but great gulps of the microbial world will also disappear in the depths of this planetary holocaust…

Exact dates are not known, but mankind’s final fate can be seen scrawled upon the familiar checklist for mass extinctions which we are quickly ticking off, one by one. As Ward points out, every time there has been a major disruption in Earth’s delicate biogeochemical carbon cycle, there has been a mass extinction. Today that disruption is happening on a timescale much faster than at any time in the past, even faster than the asteroid impact that killed off the dinosaurs. During the K-T extinction, the immediate impact of the asteroid killed only the large animals. It took thousands of years for the consequent climate change to kill off smaller organisms. Current trends are exponentially faster, not only with anthropogenic climate disruption incinerating the biosphere within a lifetime but also by a multi-pronged attack from other human activities such as chemical and plastic pollution, the global spread of invasive species, and humanity’s massive overdraw on the planet’s resources.

If one were to equate Earth’s geologic history to a calendar year, modern humans have been around for a mere 37 minutes while managing to consume 1/3rd of Earth’s natural resources in just the last 0.2 seconds. The biomass of wild mammals has fallen by 83% since prehistory and it is projected that by 2050 humans will have eliminated 38–46% of all biodiversity from the planet. 70% of the planet’s land area has been altered by humans, with 40% considered degraded. By 2050, an area of land the size of South America will be further degraded. Nearly all of the marine biosphere has been degraded. Now Modern man has set his sights on wringing the last dollar of profit from the already dying oceans in what is being heralded as the “Blue Acceleration”, a not-so-clever play of words on the Great Acceleration referring to the period starting around 1950 when measurements of humanity’s impact on the planet’s resources went hyperbolic:

As pressures on Earth’s land grow and terrestrial resources look increasingly exhausted, governments and corporations are seeing the next big wins on, in and under the high seas. Whether it is mineral exploration, shipping, energy, tourism, desalination, cable laying, bioprospecting or more, ocean-based industries are picking up speed fast.

This “blue acceleration” has many people worried…With the power to profit from remote ocean resources growing rapidly, and the laws that govern their exploitation less than clear, we risk a free-for-all in the deep. “Our society has been based on the degradation of nature, destruction of nature,” says marine ecologist Enric Sala…

The new plunge into the ocean has come about in part because technologies – from ocean drilling and offshore wind turbines to desalination plants and factory trawlers – have made it possible. “A lot of offshore industries were unthinkable even just a few decades ago,” says Jouffray.

And so it goes, Homo sapiens onward march of eating the seed corn and leaving a husk of a planet for future generations …if there are to be any.

Back to Peter Ward and that checklist for mass extinction…The second step after a large release of heat trapping gasses is that Earth’s poles will start warming up much faster than the rest of the globe, melting the polar icecaps and reducing the heat differential between the equator and higher latitudes. A recent study found that the Arctic is heating up as much as seven times faster than the global average. The Antarctic is warming four times faster than the global average. This diminishing heat differential between the higher latitudes and the equator leads to the third step which is that ocean currents and atmospheric jet streams slow down and become stagnant and swampish. As professor Ward points out, swamps have a lot of nasty, toxic aspects to them such as hydrogen sulfide. This has happened to the oceans many times in Earth’s history with deadly consequences, the most recent being the PETM extinction which was associated with the largest deep-sea mass extinction event in the last 93 million years. Less than 5% of sea creatures survived. The oceans became a poisonous and miasmic brew of acidification, hypoxia and sulfide gases. Deep ocean upwellings injected hydrogen sulfide into the atmosphere, laying waste to plants and animals. This killer gas rose to the upper atmosphere and also attacked the ozone layer, allowing deadly ultraviolet radiation from the sun to amplify the destruction of plant and animal life. Fossil spores contained in strata from the PETM extinction show deformities consistent with damage from UV radiation. Major disruptions in the hydrologic cycle occurred with evidence of increased continental runoff. Land suffered extreme precipitation events. Dinoflagellates, tiny organisms that ooze toxins and create deadly algal blooms called ‘red tides’, flourished in the nearly 100°F surface water of the equator. Less than a third of the large animal species made it. Nearly all trees died. No ice existed on the planet during that time. Sea levels were around 300 feet higher than now.

Today we are pumping heat trapping gases into the atmosphere nine to tens times higher than during the PETM extinction. We are just four generations away from matching the chemical composition of the atmosphere that caused that die-off event. However, we are already seeing major changes in the Earth’s climate system that align with the third step toward a mass extinction. Proxy data (like coral data, ocean sediments, and land-based data) along with modern-day instrumentation show an intense weakening of the AMOC, Atlantic Meridional Overturning Circulation, in the past 200 years. And the Gulf Steam, a component of the AMOC, is also showing signs of collapse. We are in the process of turning off the global ocean conveyor belt that keeps the ocean oxygenated and helps regulate the Earth’s climate. Ocean acidity has increased about 30% from preindustrial times to the early 21st century, a pace faster than any known in Earth’s geologic past. The volume of anoxic ocean waters has quadrupled since the 1960s, and evidence suggests that temperature increases explain about 50% of oxygen loss in the upper 1000 meters of the ocean. Ocean stratification due to climate change has increased 18% in the top 150 meters of the oceans since 1960. Stratified ocean layers have a number of negative effects such as preventing the mixing and transport of heat, carbon dioxide, oxygen, and nutrients to the lower depths of the oceans. It was only recently, November 2021, that a group of scientists issued a plea to governments for establishing a global monitoring system to track the loss of oxygen in the oceans causing dead zones:

“There is a pressing need to document and predict hypoxic episodes and hotspots of low oxygen in order to take protective actions for aquaculture, put in place precautionary measures for affected fisheries, and monitor the wellbeing of important fish stocks,” Limburg said.

“Without this understanding, we are in the dark about impacts that have large economic-ecological implications.”…

“These problems are getting worse because we are not solving the problems of nutrient run-off and our waters are continuing to warm.

Stalled Rossby waves in the Jet Stream linked to extreme weather events have increased significantly in the last twenty years. U.S. crop losses due to drought and flooding have trippled since 1995. Onward we march into oblivion.

Despite the horrors described thus far, what really scares Professor Ward is sea level rise. Ward believes that the volcano of mankind will sputter out before we reach the levels required for a full-fledged Canfield Ocean, and negative feedback loops in the climate system will pull Earth back from the brink. The “Canfield Ocean”, a sulfidic and partially oxic ocean, existed for more than 40% of Earth history, between the Archean and Ediacaran periods. It would take millennia to reach that state again, but humans are supercharging the process to get there by releasing into the ocean vast quantities of nutrients from agricultural fertilizer, soil erosion, industrial waste and sewage, in addition to the ever-growing release of CO2 and methane emissions. Humans have become a geologic force breaching most if not all of the planetary boundaries that make Earth hospitable for life. The mechanisms required for Earth to return to a dead, toxic planet may have already been irreversibly set into motion.

Getting back to Ward’s fear, the most recent report on sea level rise states that it is accelerating with an increase of one foot expected along U.S. coasts by 2050. And that is only if emissions are curbed now. Otherwise, expect up to 5 feet. The researchers say that one foot of SLR over the next three decades is equal to the total that occurred over the past century. Just one foot of vertical rise in sea level will swallow up 100 feet of shoreline if the slope is just 1% or more, a typical slope for most coastlines. To make matters worse, most coastal cities are sinking at a rate faster than the seas are rising. Thus within the next few decades, we could see several hundred feet of shoreline swallowed up along coasts of America and around the world, creating the largest human migration in history. Ward believes we’ll have six feet of sea level rise by 2080 which will destroy a big percentage of the world’s rice production, primarily through salinization. Rice is the number one food source for a majority of the world population today. Sea level rise alone could devastate global trade, not to mention the inevitable damage to ports from stronger storms. The latest IPCC report made it clear that parts of the planet are fast becoming uninhabitable:

Life in some locations on the planet is rapidly reaching the point where it will be too hot for the species that live there to survive, international climate experts said in a report Monday.

“With climate change, some parts of the planet will become uninhabitable,” said German scientist Hans-Otto Pörtner, co-chair of Working Group II for the Intergovernmental Panel on Climate Change (IPCC), which produced the report released in Berlin…

…Increased heat waves, droughts and floods are already exceeding plants’ and animals’ tolerance thresholds, driving mass mortalities in species such as trees and corals, according to the report…

…Sherilee Harper, a lead author on the North American chapter and an associate professor at the University of Alberta’s public health school, said she was personally struck by the effect climate change already is having on the “physical and mental health of many Americans.”

Peter Ward then brings up something I don’t remember hearing about global warming. The higher temperatures are disrupting the sperm fertility of organisms. Ward says it’s an existential threat to the amount of food we can produce. Recent studies show this to be true and the damage continues across generations:

…according to new research. New findings reveal that heatwaves damage sperm in insects – with negative impacts for fertility across generations. The research team say that male infertility during heatwaves could help to explain why climate change is having such an impact on species populations, including climate-related extinctions in recent years.

Nate and Peter then get into the societal ignorance preventing humans from addressing any serious problem, let alone the existential threat of anthropogenic climate disruption. Peter says, “How could we, as a species, take something as simple as masks and turn it into a political ploy where the level of ignorance will kill you, will kill you?!?” Nate then explains how social media algorithms are set up to highlight the most polarizing content in order to generate more user activity since their business model is based on user engagement. In order to keep users online, the social media platforms are also designed to be very addictive such as with the infinite scroll feature and the “like” button.

In 2017, Facebook’s former president, Sean Parker, said publicly that the company sought to consume users’ time as much as possible, and that the act was “exploiting a vulnerability in human psychology”…”That means that we needed to sort of give you a little dopamine hit every once in a while because someone liked or commented on a photo or a post or whatever… It’s a social validation feedback loop… You’re exploiting a vulnerability in human psychology…” – link

There is no fixing this dysfunctional social media ecosystem because it is operating exactly as intended. Our profit-driven economic system is rooted in inequality, exploitation, dispossession, and environmental destruction. And encouraging the public to turn off the horror show of climate chaos and biodiversity annihilation are essential for this system to continue. Exploiting tribal biases is a good way to keep the plebs fighting amongst themselves as the last dollar is extracted from a dying planet. Nate asks, “If we can’t have a discussion on what’s real or not with COVID, how are we going to have one about the ocean’s ecosystems and Earth systems and our collective future?” Indeed.

“I’m telling you that we’re putting our kids onto a global school bus that will with 98% probability end in a deadly crash.” ~ Hans Joachim Schellnhuber, Director Emeritus of Potsdam Institute

I recently saw the movie ‘Don’t Look Up’ after avoiding it since its release and I must say, that movie mirrors the tragic state of our society to a T. When you see Dr. Randall Mindy (DiCaprio) finally losing his cool, raging against a shallow, celebrity-idolizing, commercialized society on some glib TV talk show, this was not a stretch for the actor (an ardent environmental activist) who simply had to replace the oncoming fictional comet with the asteroid of abrupt climate change currently bearing down on us. At first, no one will listen to the scientist’s warning, not even the President of the United States Janie Orlean (Meryl Streep) who is more worried about her polling numbers and keeping her campaign contributors happy than being bothered by an existential threat to civilization. Once tech guru Peter Isherwell (Mark Rylance) plants a bug in the President’s ear about how the comet could be exploited for its trillions of dollars worth of rare earth minerals, then all bets are off for deflecting the oncoming catastrophe. The creepy Techno-Utopist Isherwell reflects our own society’s blind worship of technology and consumerism as the answer to all its ills, when in reality they are only further alienating us from the natural world that underpins our survival. Throughout the movie, there are beautiful clips of nature that briefly flash across the screen, reminding me of what we are losing in our ongoing sixth mass extinction. Modern man and the havoc he is wreaking on the planet is happening in a microsecond when viewed in geologic time scales, but humans have trouble seeing it because we live an ephemeral existence, easily inured to an ever impoverished world.

Labeling the comet’s collision course with Earth as mere fear-mongering, politicians and TV talking heads manage to politicize the threat amongst the population, hence the title of the movie. Throngs of mindless people attending political rallies while wearing trucker caps with the slogan ‘Don’t Look Up’ reminded me of scenes from the MAGA crowd in thrall to their grift-scheming conman. Those who speak too much about the reality of the approaching comet are ziptied, blinded with a hood over their head, hauled off to an undisclosed location, and compelled to stay quiet by the authorities. In our real world, a fate much worse than that awaits those who oppose fossil fuel companies, miners, loggers, and others who are destroying the planet. Only when the comet and its long tail become clearly visible in the sky do people take the threat seriously, but by then it is too late. Back to reality, there’s no indication that such a tipping point in public consciousness has changed our trajectory towards ecological disintegration and collapse of civilization. Near the end of the movie as the planet-killing comet is colliding with Earth, Dr. Mindy’s family and a few of his colleagues are holding hands at their last supper and Dr. Mindy says, “We really did have everything, didn’t we?” The same can be said of what we are losing in today’s unfolding anthropogenic mass extinction. A thousand species a day, each a product of eons of evolution and designed for a specific purpose, being permanently erased from this planet along with any sort of stable and predictable climate means we are trashing Eden and descending into the hellscape depicted in Bosch’s Garden of Earthly Delights. This most recent study confirms past warnings:

“Drastically increased rates of species extinctions and declining abundances of many animal and plant populations are well documented, yet some deny that these phenomena amount to mass extinction,” said Robert Cowie, lead author of the study, in a press release. “This denial is based on a highly biased assessment of the crisis which focuses on mammals and birds and ignores invertebrates, which of course constitute the great majority of biodiversity.”…“Dedicated conservation biologists and conservation agencies are doing what they can, focused mainly on threatened birds and mammals, among which some species may be saved from the extinction that would otherwise ensue,” the paper said. “But we are pessimistic about the fate of most of the Earth’s biodiversity, much of which is going to vanish without us ever knowing of its existence.”…The researchers write that it is crucial to fight against the crisis and manipulating it is an abrogation of moral responsibility.

Of course the ones in charge, blinded by their greedy dream to profit from an oncoming disaster, surreptitiously escape Earth on a rocket ship, cryogenically preserved until they reach a distant Earth-like planet in the Goldilocks Zone of another solar system. This colonization of some other habitable planet by Earth-bound humans is a fetish amongst techno-optimists and futurists, but it is a pipe-dream not only because it is impossible due to basic biological constraints and technological infeasibility but also for the simple reason that if we cannot keep our house in order here on the planet that gave birth to us, we don’t deserve another chance. And for God’s sake, can Elon Musk stop ranting that humans have to get off Earth because all life will be snuffed out after the sun theoretically expands into a giant red star five billion years from now? Just as in the movie, our tech demigods will lead us over the cliff while planning their own getaway to a private underground bunker or second homes far away in some distant country. It is frightening to think that we are only seeing the beginning of this unfolding global ecological apocalypse that will affect every living thing on Earth. Nearly all past mass extinctions have occurred due to a disruption of the carbon cycle, only now it is happening at a rate of speed multiple times faster than previous ones and with humans serving as the architect of their own demise. In the last 500 million years, across 6 mass extinctions and the countless rise and fall of global temperatures and sea levels, the only time the climate changed faster was 66 million years ago when Earth got hit by a 10km asteroid that killed off 75% of all species. Mass extinction events turn freshwater bodies into toxic soup, and we’re seeing the same thing happen today. But fret not, technology will save us and stock prices are up this week, not to mention that our social media rankings are going gangbusters.

It has been said that when civilizations begin to die, they go insane. Perhaps Stoicism and Buddhism are the most useful philosophies in an age where the future is bleak and no one seems to be facing reality. After half a century of dire warnings from noted scientists, numerous Climate ~~Action~~ Inaction Summits (rigged to fail), revelations of decades-old climate studies from Fossil Fuel Corporations themselves proving all along that they knew, and worsening extreme weather events as well as the planet’s quickly disappearing cryosphere (what happens in the Arctic does not stay in the Arctic), here is where we stand today:

The world’s insatiable appetite for electricity is setting up a climate disaster

A report published Friday by the International Energy Agency found that global demand for electricity surged 6% in 2021, fueled by a colder winter and the dramatic economic rebound from the pandemic. That drove both prices and carbon emissions to new records.

The growth in demand was particularly intense in China, where it jumped by about 10%…

…Electricity generated by renewables grew by 6% globally last year, while coal-fired generation leaped 9% due to high demand and skyrocketing natural gas prices, which made it look like a more attractive option.

Carbon dioxide emissions from power generation rose 7% as a result, reaching an all-time high after declining the previous two years…

…The IEA found that emissions from the power sector will “remain around the same level from 2021 to 2024,” even though they need to decline “sharply” for the world to limit global warming to 1.5 degrees Celsius and avoid the worst effects of climate change.

As physicist Tim Garrett has pointed out, “Any new energy source adds impetus to the conversion of raw resources into the stuff of civilization, accelerating growth and future demands for all energy types. Renewables add to the consumption, they do not replace.” Also, gains in energy efficiency are simply supplanted by more growth.

Keep in mind that even if we were to magically reduce our CO2 emissions overnight, the opposite of what is happening, we will never again see the climate we grew up in. It is never returning. Realize that the current level of CO2 equivalent GHGs already exceeds 500 ppm. The increased pace of extreme weather events we are now getting from climate change is shocking even those scientists who predicted it. The Arctic is greening with the treeline advancing northward 40 to 50 meters every year from what was once an annual increase of only a few centimeters. Adding yet another pernicious feedback loop to the climate crisis, beavers are moving into the warming Arctic in greater numbers and radically transforming the landscape with their dams, further accelerating the thaw of permafrost that releases methane and carbon dioxide into the atmosphere. A worrying new study shows Earth’s ability to reflect solar radiation is weakening — as the ocean is heating it is failing to generate clouds that reflect back sunlight. Astoundingly, half of that weakening has happened in the last four years:

“The albedo drop was such a surprise to us when we analyzed the last 3 years of data – many scientists hoped that a warmer Earth may lead to more clouds and higher albedo which would then help to moderate warming and balance the climate system But this shows the opposite is true”

If this trend of Earth dimming due to climate change continues, climate models will have to (once more) be significantly revised to include this additional net warming. We are headed for a Miocene climate during which the Antarctic ice volume was half of what it is today and the Arctic Ocean was ice-free in winter. Sea levels were 130 feet or higher and temperatures were about 5 to 8ºC warmer. Our ancestors were apes at that time. The European shoreline was 120 miles inland from today’s coast and dense swamp-forests resembling modern Louisiana clogged coasts and estuaries in Denmark and Germany. Nothing living in its region today is adapted to what will come. Remember those trees in the Pacific Northwest that sizzled in the heatwave of last year’s summer? A new study paints a dire picture for their future, as well as ours:

“By some estimates, it’s probably the largest scorch event in history,” Oregon State University researcher Christopher Still told OPB’s “Think Out Loud” on Monday. “I mean this is a new thing for us to be seeing on Earth, so it’s sort of a dubious milestone.”…

…“If this just keeps going, if these are happening every five or 10 years, it’s gonna be really grim I think for most of the forests of the Pacific Northwest.”

As the saying goes, “Lessons in life will be repeated until they are learned.” And so humans have yet to understand their place in the world, punch drunk on more than a century-long bacchanalia of fossil fuel burning. In the end, nature will put us in our place, and not in a good way. It is interesting to note that right around the peak of industrial civilization’s collapse, humans will have evidently lost their biological ability reproduce due to chemical pollution. We have saturated the Earth with so many and so much chemicals that we have breached another planetary boundary:

The cocktail of chemical pollution that pervades the planet now threatens the stability of global ecosystems upon which humanity depends, scientists have said.

Plastics are of particularly high concern, they said, along with 350,000 synthetic chemicals including pesticides, industrial compounds and antibiotics. Plastic pollution is now found from the summit of Mount Everest to the deepest oceans, and some toxic chemicals, such as PCBs, are long-lasting and widespread.

The study concludes that chemical pollution has crossed a “planetary boundary”, the point at which human-made changes to the Earth push it outside the stable environment of the last 10,000 years.

“There has been a fiftyfold increase in the production of chemicals since 1950 and this is projected to triple again by 2050,” said Patricia Villarrubia-Gómez, a PhD candidate and research assistant at the Stockholm Resilience Centre (SRC) who was part of the study team. “The pace that societies are producing and releasing new chemicals into the environment is not consistent with staying within a safe operating space for humanity.”

Pfft!!! Just another fancy-schmancy warning by some pedantic scientists for the world to ignore. No need to worry, we can live in hermetically sealed bubbles that filter out all that nasty stuff, can’t we? All of our socializing and entertainment take place indoors on digital screens anyway, doesn’t it? But wait, there’s more. The Doomsday Glacier is coming for us. The Thwaites Glacier is the size of Florida and it is cracking apart on the surface and melting from below, loosening its anchor on the undersea mountain that holds it in place. If this glacier goes, it could unleash much more ice from the West Antarctic ice sheet that is held in place behind it, causing an immediate and catastrophic effect (10 feet) of sea level rise. One scientist says it could go within a few years. This development falls in line with what another expert, Professor Harold R. Wanless, had said years ago about sea level rise and climate change—that sea level rise does not happen in a gradual and linear fashion but rather as sudden, large pulses. I blogged about him six years ago, and what he said back then in the context of what is happening now gives me chills:

…Subsequent ice melt was not a gradual acceleration and then deceleration process. Rather it was a series of very rapid pulses of sea level rise followed by pauses. These rapid pulses of rise, from three to thirty feet, were fast enough to leave drowned reefs, sandy barrier islands, tidal inlet deltas, and other coastal deposits abandoned across the continental shelf. That is what happens when climate change warms enough to destabilize some ice sheet sector. It rapidly disintegrates, resulting in a rapid rise.

Just a couple years ago, a study of ancient ice in the West Antarctic Ice Sheet showed that multiple meters of sea level rise occurred from less than 2ºC of warming at the beginning of the last interglacial period. As we are once again witnessing today, the West Antarctic Ice Sheet is highly sensitive to collapse from slight temperature increases.

Circling back to the movie I was discussing earlier, there is a scene in which junior astronomer and Ph.D. student Kate Dibiasky (Jennifer Lawrence) is with a group of disaffected youth who are discussing conspiracy theories regarding the global elite, and Dibiasky says in an exasperated voice, “You guys, the truth is way more depressing. They’re not even smart enough to be as evil as you’re giving them credit for.” Perhaps the truth is even more depressing than that. In the grand scheme of things, free will appears to be nothing more than a figment of our imagination. Like microbes proliferating in a Petri dish and dying off after overshooting their confines, humans are essentially replicating the same process albeit on a planetary scale. Evidently, we are biologically programmed to eventually crash and burn. Just as with all other species, humans have the imperative to expand their numbers, exploiting all resources until stopped by environmental constraints, and those limits to growth are fast approaching as we speak.

A Second Trump Term Will Prove Even More Deadly For Americans

“It’s going to disappear. One day it’s like a miracle – it will disappear.” ~ Trump

Who would have guessed that a reality TV “star”, con-artist, and political hack would be the one person to shake America’s institutions of government to their core? Then again, Hitler was a down-and-out artist before he became a dictator. Lots of people warned that this time with D.J. Trump would come even before he finagled his way into the White House. From his days of swindling hundreds, if not thousands, of small business contractors and workers to laundering money and defrauding the U.S. government, his tenure as president has been no less riddled with corruption, back-stabbing, lying, and cheating. Since Trump cannot retain power through the traditional means of tinpot dictators via military coup, he is using an army of lawyers who will question every mail-in ballot and use every legal maneuver in an attempt to render the 2020 election results null and void. This summer, Trump began a campaign to sabotage mail-in voting after falsely claiming it was fraught with fraud and then hiring one of his unscrupulous cronies, GOP Megadonor Louis DeJoy, to cripple the U.S. postal service. However, the GOP plan to destroy majority rule really kicked into gear with their ‘gerrymandering on steroids’ strategy which was hatched more than a decade ago when right-wing strategists concluded that taking over state legislatures would enable them to redraw districts and control the outcome of elections.

Over the last four years, Trump has amassed a laundry list of skuldugery such as abusing his high office to delegitimize any reporting critical of his administration by labeling it “fake news”, exacerbating an atmosphere of doubt, mistrust, and suspicion of the government by perpetuating numerous conspiracy theories, stoking racial tensions with incendiary rhetoric while ignoring the mounting anger over police brutality, perverting the rule of law by stacking the courts with unqualified GOP-friendly judges, installing a henchman named William Barr to run the DOJ and help give the president autocratic powers, and politicizing science by censoring government researchers and dismantling science-based health and safety protections. All of these tactics have been used by dictators of foreign countries to eliminate opposition leaders and control the population. Muzzling of scientists is a global problem that is getting worse. Trump has single handedly made the US a pariah on the world stage as he cozies up to dictators while belittling and undercutting traditional Western allies. In fact, America’s reputation in the world is the lowest it’s been since such surveys began two decades ago. There’s no hiding that Trump would love nothing more than to turn America into a Russian-style dictatorship where he could rule for life, rob the public purse at will, and kill dissidents with impunity.

Had Trump properly handled the pandemic that continues to upend the economy and ravage people’s lives, 90% of U.S. coronavirus pandemic fatalities could have been prevented. Life would be drastically different from what we are experiencing today. By January 2021, pandemic fatalities in the U.S. are projected to more than double from their current number of over 200,000. This will be Trump’s macabre achievement for his criminally negligent handling of this pandemic. He was able to do much more than when he proclaimed he could stand on 5th Avenue, shoot someone, and get away with it. In fact, due to his lack of leadership, downplaying of the virus, obfuscation of CDC reporting, and failure to enact a coherent national plan, he will have killed more Americans than whom died in World War II. By comparison, that’s twenty-five to fifty times the number of Americans who die on average in any given year from the flu. Trump may blame China, the WHO, Democrats, or anyone else for unleashing this plague, but it was his deliberate and willful abdication of his duty as president to protect public health and safety that has created his coronavirus killing fields. Who hasn’t heard the Bob Woodward tapes from early February 2020 of Trump explicitly saying that the virus is much more deadly than any strenuous flu and extremely contagious? All the while he has downplayed the danger to the public, even going so far as to say it was a “hoax” by the Democrats? To this very day, he perpetuates these lies while corralling his cult followers into close quarters for his self-aggrandizing MAGA rallies. His followers are oblivious to the fact that they serve as nothing more than disposable props at these grotesque events. He mocks masks, the most effectiive tool we have against the virus. He likes to claim that his China travel ban saved many lives but, like so many things he says, the opposite is true. His ban had many holes and actually may have worsened the outbreak in the United States. In addition, Trump’s downplaying of the virus has allowed it to fester in the U.S. and likely mutate into a more contagious strain; whether it transforms into something more deadly is all a matter of a genetic roll of the dice. Experts are fearing a double whammy from both the flu and the COVID-19 coronavirus this winter.

With historic megafires raging along the entire west coast in the new normal of inferno seasons, Trump tells climate scientists directly to their face that “it will get colder, just wait and see” and “I don’t think science knows about climate.” In the meantime, he’ll be spending millions shoring up his golf course properties from the rising seas. Over eight feet of sea level rise is already locked in from Antarctic ice melt alone, even if Paris climate agreements are fulfilled. As Biden says, Trump is a “climate arsonist.” At this point, I cannot help but view anyone who supports this catastrophic president as anything other than a traitor to their own country.

At a time where compassion and honesty are most in need as our civilization runs headlong into the limits of a finite planet, the world appears to be going in the opposite direction of more magical thinking, selfish nationalism, and diminishing human rights. The destruction Trump has done is real and four more years of him will guarantee further damage for decades to come. For instance, many of the dozens of environmental regulations that Trump has rolled back will likely be permanently cemented into place by Trump-appointed judges. These rollbacks are already causing countless premature deaths in the U.S. The amount of carbon his legislative actions will have put into the atmosphere by 2035 is estimated to be the equivalent of Russia’s annual emissions. The EPA will become a shell of its former self, having been completely usurped by corporate interests to pollute without restraint. Other countries are already following America’s lead of completely disregarding the threat of anthropogenic climate disruption. Any semblance of democracy will be shredded as Trump’s swamp of greed, corruption, and white nationalism runs amok. Conspiracy theories will run rampant as daily life becomes ever more precarious in a climate of fear and science becomes completely subjugated by economy, polity, and religion. There is a prescient quote from Carl Sagan that warns of the dystopian world we are well on our way to creating:

“I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness…

The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance”
~ Carl Sagan, The Demon-Haunted World: Science as a Candle in the Dark

I shudder to think of the hellscape that awaits us with another term of Trumpian chaos. There are only two choices before us in our American corporatocracy, so let’s be pragmatic about our dire situation. I’ll take take Biden, the corporate friendly centrist who has a plan to contain the virus and a two trillion dollar climate change strategy, any day of the week over Trump, a corporate fascist masquerading as a populist who never had any national plan to effectively contain the virus and believes climate change is a hoax. Of course there are many other issues that make Biden the sane choice between the two. It’s comical how the Right-wing propaganda machine has painted Biden as some sort of bumbling socialist puppet, especially when you consider that Wall Street’s own analysts say that a Biden administration would be neutral to positive for them. Under Trump’s direction, the very wealthy were given big tax breaks that allowed them to pay less than the working class for the first time in history. And due to Trump’s gross mismanagement, our government’s budget deficit will soon exceed the size of the nation’s entire economy for the first time since World War II. A growing body count of dead Americans that rivals the biggest war fatalities in our nation’s history is happening as a result of Trump’s sociopathic response. Trump’s latest hairbrained scheme is to allow the American population to build herd immunity to the novel virus. Never mind that in the process we would incur fatalities in the millions and collapse the healthcare system which would raise the death toll even higher, or the fact that scientists doubt the population would even ever be able to reach such levels of immunity. Someone, please tell me how Trump has made America great again.
